transmission down!!!

[alvaro.noriega]

So I was cruising down the freeway when I heard a loud "crack" and fluid and smoke started billowing out from behind the car. Turns out it was the transmission. The problem is I don't know what caused it. So I took out the transmission and this is what I found...

A big hole in the case...


Closer look at the hole.


The clutch looked perfectly fine and happy.


So after seeing this I have no idea what could have caused this. Does anybody have any ideas?

Typ diff pin failure! Sorry!!
do a search
there are 2 short diff pins & 1 long diff pin in the Differential. they are held in place with a roll pin. when a roll pin breaks the pin spins & eventually ejects. common causes can be burnouts & one wheel peels around a corner. this puts a lot of stress on the spider gear held by the diff pin.

The big gear you see there is the differential. I'm going to go with blown diff pin.

diff pin FTW sorry but i dont know what part of cali you are in but their is a tranny i found for $450 with only 66k on it here is their info: Capital Auto Wrecking USA-CA(Gardena) 1-323-321-1234. it is a 1992 tranny if they ask

 

[zach44102]

sorry man. im dreading the day my dif pin goes but i do know eventually it will. i would buy a wavetrack why your at it. or weld the diff pins on your next tranny

 

[zach44102]

i guess i should of knocked on wood because my damn diff pin blew out today!!!!

Once you find a replacement trans....

get yourself one of these....

:sun:

That's a real bummer. BTDT.

When you get your replacement MTX, get the diff REINFORCED!!!!!

This is cheap and easy to do. There are a few member's on here (like me) that offer this service.:wave:

The CORRECT way to permanently fix the problem is a Quaife or Wave Trac diff.

ya don't say? shocker...

 

[AREA 91]

Do not throw any mtx parts away!!!!!

 

[zach44102]

yep punched a hole through the case too. is a welded diff fix it permanently or can it still fail? if u where to compare wavetrack to a welded diff whats the pros and cons

 

[NotSoSlowSHO]

Welded diff = permanent fix

But it is still an "open" diff that will exhibit the traditional one-wheel-peel


No SHOboom though!

 

[zach44102]

ok well i wish i had 1400$ for a wavetrack but i think ill be welding my new trans. im getting a stage 2 clutch. what els do ineed to replace while im at it?

 

[SuperHO]

Get the SHONut ceramic throw out bearing, new axle seals, replace your rear main whilst in there, check to see if your flywheel needs resurfacing, subframe bushings (if not already replaced), reinforced tranny and motor mounts, wheel bearings..


There's a lot you can do for preventive maintenance while the car's apart. I'd take advantage of it.



*edit

And to the OP...that hole ain't that big. My last one had fist sized holes on BOTH sides. After your 4th or 5th diff pin grenades, it becomes routine and you don't even think about it anymore.

 

[zach44102]

thanks for the list. i have most so i think im looking at asfb, clutch, welded diff, rod shift bushing. and i probably will get the flywheel resurfished. i will be buying a used tranny. as long as it is working properly i shouldent have problems welding my diff should i?

 

[luigisho]

No. Other than fitment during reassembly as noted above. There should be a saved thread or two about doing this somewhere.

All of a sudden all of those Burnouts and "Drifting" in the snow was not such a good Idea, Now was it?
