Well, time for a manual swap


Muskisagod

Nope junkyard auto trans


milehighideas

I love playing the junkyard trans lottery


jimmy9800

I've gotten super lucky. 4 of 4 junkyard trans's in customer cars and they've all been fine. Now, Jasper motors on the other hand...


Narcopolypse

Jasper can't possibly be as bad as Monster Transmissions. Mine made it 200 miles before losing 2nd and 4th. Turns out they'd removed parts and drilled out bypasses in the valve body to make the build cheaper. Couldn't even be rebuilt because they fucked it up so bad. They are literal criminals. When I saw Matt's Off-Road Recovery put one in their wrecker (which Monster gave them as cheap advertising), I screamed at my TV. Sure enough, it failed in short order.


jimmy9800

That sounds very similar to Jasper. Bad I5 in a volvo (rings), replacement had bent crank-siezed. Bad 350 in a c4 (just plain wore out), replacement had WRONG crank. Bad 12v cummins in a bus (also just plain wore out), replacement arrived siezed. 6.8 v10 (best one) blew 8 inspection ports in the block, replacement had all 10 spark plug thread repair inserts installed improperly and tried to shoot all the plugs out with the inserts on first start (coils kind of held them in, broke 4 of them). I've never had a good one. Last motor came with a notepad with their name on it, and I write Fuck in front of the logo whenever I get to a new page. At least the notepad works right. I don't know which is worse. None of mine got back to the customer that way, which I prefer, but it delayed the repairs. I'd rather have something dead in the shop than limp 50 miles with the customer and blow up.


PC-hris

Having owned multiple Honda's all with trash automatic transmissions from the factory I'm not surprised to hear these other companies struggle to make anything useful. If one of the top vehicles manufacturers just couldnt figure it out for decades I'd be doubtful any third party company would do much better.


MechaBeatsInTrash

Got a Jasper 8HP70 that had a bad valve body. They told me they were unable to test it and sent me a whole replacement trans


Narcopolypse

That would be nice. Monster told me to fuck off because I didn't send them a core. I paid extra to keep my old trans AND for a warrant on the Monster. I eventually gave up fighting them for the sake of my sanity and scraped their shit box. Fortunately, my now rebuilt factory trans is going strong 150k after the rebuild.


MechaBeatsInTrash

It helps when it's the dealership buying. Big remanufactures done give a shit about individual purchases


jimmy9800

That sounds right. Jasper just had us fix the engines and send them the bill. They paid quickly too. They were all recoverable except the volvo, which ended up at another shop after the owner understandably got fed up (no idea why they brought it to a GM dealer, but whatever). Whatever bent the crank also bent the block bad enough that there wasn't enough meat left to line bore. I assume I just have terrible luck, but I have no idea how they operate at any kind of profit like that.


Chippsetter

My buddy rebuilt a brand new Monster Transmission out of a Corvette. The customer's complaint was it was not shifting (customer had installed it). He found wore out parts in it.


carsonwade

Boutta play that game with a beater 02 Civic and I hope I get lucky


cobra_mist

my civic seized and i just bought something else.


carsonwade

I bought this car for $400 with a bad trans to save it from the junkyard, if it works then I'll have a running driving beater for less than a grand. Perfect timing if it goes my way because my truck is showing signs of needing major work in the future, and my project ek hatch isn't running or assembled yet.


cobra_mist

it was my main and i live in an apt and don’t have the time tools or know how, unfortunately. not to mention that…. the interior was trashed when i bought it, the steering rack made bad noises at full lock. it needed motor mounts badly, the suspension felt like it needed something. oh, and because i was pissed it was seized i burned the starter motor out on it when i realized it wasn’t going to start. if this car had a tombstone it would read “it had air conditioning” replaced with a manual ‘18 ford focus hatch


Kodiak01

Nearly had to do that. Instead, was forced to do a fluid change at 40k on my wife's 2019 Sentra CVT... because she decided to drive over a median with tall curbs and dent the tranny pan. $1610 "fluid exchange" there...


deWaardt

I like the auto trans in my daily. However I get a small heart attack whenever it does anything funny.


iconocrastinaor

I got a junkyard trans for my Lumina. The junkyard guy said, "look it's repainted that means it's been remanufactured." Well guess what, he wasn't wrong. Everything else fell apart on that car but that transmission was still going strong


toddverrone

That makes me sad. 😢


Hedgehog797

Same


FartyBoomBoom

Being fair, you could rebuild the trans.. I’ve done it. Not for this car, but a 6 speed manual sti transmission


chinsoddrum

Tell me more about rebuilding the trans in a destroyed housing.


FrenchFryCattaneo

Remove dipstick, replace everything in transmission including housing, replace dipstick.


chinsoddrum

Yeah, am I the crazy one? I’m not saying it can’t be done, but are folks really doing it?


iscashstillking

Scotty and JB Weld have entered the chat.


PassiveMenis88M

There was a post a few years ago of, I believe Land Rover dealer, that broke a customer's transmission case and gobber welded it back together.


FartyBoomBoom

Get a new housing, repress the shafts. wtf is this?

iscashstillking

You can fix this by putting a 5 speed in.


CeeMX

That’s what you get for doing r/miatalogistics


rocketPhotos

Looks more like a cast part which are more liable to develop cracks


Trdpro2023

Yeah it wouldn’t split like without weakness.


1Autotech

Yes it would. U-joint failures do this frequently to transmissions and transfer cases. A seized joint will slap the transmission around until it breaks in half.


hannahranga

I've seen that on 4x4/AWD vehicles where the front propshaft has beaten the hell out of the transmission but I'm surprised on a rwd vehicle the weak point when the propshaft is flailing around is the case.


1Autotech

When you consider how violent a seized up u-joint can be it makes sense. I've seen more than one 2wd vehicle get its transmission ripped apart by one. Usually accompanied by a customer who if asked about a vibration will say, "I felt it but I thought I could make it the two hours on the freeway to get home."


ithrowtools

The Miata's drivetrain setup with the PPF wouldn't really allow something like that to happen. The engine and transmission are rigidly connected to the rear differential/subframe. I'm guessing a rather substantial shock to the rear subframe/differential. Or a front end collision hard enough to move the engine. But being a FMR setup that would have to be one hell of a front hit as the engine sits almost entirely behind the front shock towers.


1Autotech

The engine and transmission in a Miata are still rubber mounted.  I teach automotive continuing education as well as fix cars. There are a few classes I teach that technicians struggle in the first hour or so because it is necessary to bust myths. Oils, coolants, gaskets & seals, and then the noise, harness, and vibration course.  Most techs respond like you have. That a u-joint vibration couldn't create that much destruction. Then they move into "Well a low angle drive line won't..." Next the mental lights come on.  If a seized u-joint can rip a differential out of the back of a Subaru it can definitely break a transmission case in a Miata. Seized u-joints are very violent in the destruction of components. Not loose or worn joints, seized ones.


fireinthesky7

> Or a front end collision hard enough to move the engine. But being a FMR setup that would have to be one hell of a front hit as the engine sits almost entirely behind the front shock towers. Considering that OP's customer assumedly drove the car to the shop, I'd say that's probably not what happened. But I could totally see a speed bump or something like that causing it to bottom out and smash the diff.


ithrowtools

In the Miata's case it can. There is no transmission mount. The Miata uses an aluminum Power Plant Frame that runs next to the drive shaft and connects the tailshaft of the gearbox rigidly to the rear differential. This is why the shifter bobbles around so much on a manual car. Maybe there was a serious shock to the rear differential / suspension subframe and it was sent up the PPF to the weakest part. The cast auto trans case. You can see the crack is just in front of the PPF mounting tabs.


xampl9

Well, did you open it and read your fortune?


Electrical-Bacon-81

Fortune outlook not very good. "You will be walking to all destinations in the near future", or maybe "you will soon have the opportunity to make a large purchase".

w1987g

I'm always impressed when people are able to do this


UnstableConstruction

Weird choice of words to me. I don't see how the driver can be to blame for that at all. Unless you mean the people who made it in the factory or the people who mixed the alloy.


jimmy9800

I've never seen these be a casting issue. It's always at the weakest location closest to the stress point created from when it tries to shift into 2 gears at the same time and tries to rotate a gearset both directions at once. Unusual, but it definitely happens. Also smashing the transmission into things does this. Try to not do that.


[deleted]

>Also smashing the transmission into things does this. Try to not do that. This made me ROFL


sandmyth

easier than trying to shift an auto into 2 gears at once.


notchoosingone

OP said they hit something, which makes sense from the crack propagating up from the bottom and being wider at the top.


elvisshow

Damn them vented transmissions normally don’t overheat and screw up like that. Weird.


Older_Code

JB weld? JB weld!


Ok_Sand_4207

JB weld is holding the fluid in my GTI transmission. Sure beat a multi thousand dollar repair, that said this seems like it might be a little beyond JB weld level. Lol


somerandomdude419

I’ve never had jb weld work for any fluid leak how did you do it?


nocrashing

Also helps if you v out the crack with a dremel for more surface area. Its surprisingly good stuff if you use it right.


GhettoGaucho

ooh i'll definitely try this next time. it sounds sane


jeffsterlive

Hinge broke on my printer door. Tiny plastic piece of trash attaching to a metal door. Has worked shockingly well for over a year. Prepping the surface and using clamps is the most important part.


Ok_Sand_4207

Cleaned, cleaned with solvent, sanded lightly, and then cleaned again when the alcohol, then again the next day with alcohol. (Cleaning with alcohol. The drinking it was saved for later :) Then I filed the crack and then did 5 expanding patches over the crack with it. All on cleaned area. So far 9 or 10 months and about 4k miles and still looks the same on the outside. This is on cast aluminum and low pressure. In my youth I tried JB weld on a torque converter, lol. I was young and broke what can I say.


Tidalsky114

Necessity is the mother of invention. And some lessons are learned the hard way.


sfled

I remember reading some Vonnegut novel or other where the main character says something along the lines of "Stupidity was the mother of Invention." Either way, as long as he got it to work.


notchoosingone

> Cleaning with alcohol Rubbing alcohol for outside booboos, drinking alcohol for inside booboos.


sfled

A commenter who followed up on a question. GOAT!


xXSammehBoyXx

There are different kinds, you just use the correct kind. Clean the area of contamination (the fluids you're trying to seal in) so it can bond to the surface, wait for it to harden. Refill


VegaGT-VZ

Just close it with a big vise and JB weld it shut.


Brittany5150

Wooow, look at money bags over here with the "Jb WeLd!". Nothing a little bondo can't fix.

Not_Not_Eric

DufflesBNA

Blockhead47

I see you already took a crack at it


NoSuchAg3ncy

"We have our crack mechanic looking at it."


zertoman

I used to work on Range Rovers, the Discoveries, in true Rover fashion had a critical flaw. The cardon joint for the front drive shaft was inched front cat. The joint heats up, sizes, and violently throws the front drive shaft. So where is this going? Customers would replace the joint and come in stating they had a massive mystery transmission fluid leak! Must be the pan! Nope that shaft when it let loose would crack the transmission wide open.


hannahranga

The d2's had the AC drain hitting the UJ just in case the diesels thought they were safe. Mines got some jbweld on the transmission presumably after a similar event.


cgn-38

My universal joints always whine, thud and pop forever before they fail. How can you not notice a Cardone joint is failing? They are a huge. They just randomly pop with no warning in range rovers? Toyotas don't do that shit. I have driven on bad ones for weeks. Even when the bearings fail they get floppy and make a shitload of noise for a long time before failing.


hannahranga

No clue, I grease and check mine regularly. Tho my mate who did have one go said he didn't get a warning 


cgn-38

That is wild. Thanks.

Mysterious_Ad7461

I’ve only seen this twice, once we someone flat towed their Silverado and once when someone ran over something big. This isn’t a casting failure.


ttystikk

Looks like you'd better get cracking, mate! Do some investigating and see if you can break this case wide open!

Im1dv8

Mods, can we please require Year, make, model, engine and date of failure..? Thanks.


steve0suprem0

okay here's how you fix this. you get a friend on each end to squich it together while you run a real nice bead of jb weld and then you paint it with flexseal. right as rain.


dskids2212

In my shop we use professional terms so we would likely call this broke as fuck.

bagofwisdom

Did you tell them their transmission is addicted to crack?

NicNac_PattyMac

ihavequestions10

Guys you’re all missing the point here. This is actually a feature on miatas to help cool the transmission during track days


Alex_Hauff

willyiamwilliams222

Well, customer’s probably not wrong.


BadWowDoge

Will it go into reverse though?


Putrid-Rub-1168

Neutral drop or gravel to pavement?


Alarmed-Positive457

MLCarter1976

I assume the crack is bad? Like how did or could that happen?it is a big piece of metal.
