You'll need to support your engine in the bay, drop the left subframe, and remove the trans out through where your driver'* strut/hub/control arm used to be. So your garage better be big enough to allow for a SIDE exit of the trans. The car itself will have to be very high to make this happen.

Do you realize that ONLY a 93 SSEi trans will work for your car?

yes i know.the1st time i put the 1 tranny it was off a 92 se and that tranny had throttle valve in i,.wich my car hasnt,so i just egnored ,but man oh man my car lagged n gas millages,dammit,dont get me started,anyways so i have to get one of a 93 SSEi.not a se.ok,got it.i did a lil research in th dealership and they told me that they might not fix my car because they dont make my tranny anymore.so i told them to do there best to find one.ima go check on them on monday.so yea,my garage is a 2 car garage.now,how high does the car have to be off the ground to make this possible in my garage?

oh and im so sorry about the spelling and grammer,its just that my key board is not working properly and yea.sorry,ill try my best..

Wren is sort-of right when he said that only a 1993 SSEi trans will work. He is assuming direct-swap, which is what most everyone here does.

Lets look at the the entire Series 1 L67 spread...1992-1995.

1992 and 1993 transmissions are inferior to the later models as many parts got upgraded (1993 was a transition year...some got the good stuff, others didn't).

1994-1995 are stronger and more refined, BUT...the electronics package is different. IF you were to find a 94/95, you MUST change out the internal harness, and drill and tap a spot in the channel plate for the 1993 trans temp switch (if you have traction control, which I think you do). But if your traction control is on the fritz already, or if you can do without it, you can leave the internal harness alone and just repin the external connector.

In any event, you MUST get the original ratio, otherwise the computer will get all dumbed out on you.

Not trying to hijack, but... are you guys telling me GM does not offer reman trannys for these cars? And are OEM GM parts hard to get for the older models?
If so, I may get a parts car and store it for parts.

Yes, GM does offer remans.

Am I correct in assuming you ran a 92SE trans in your car? We could have told you it would run like ***. Wrong gear ratios, controls, etc.

willwren,my car did run like ***,i mean,just like you said,the gear ratio was so diffrent and my car was soooooo slow and man,the gas it was hoggin,OMG.i think my car was doing like 13 mpg on freeway and no lie,it did like 9 mpg on city.so yea,this time,im going to put a 93 ssei tranny on my car,yet,the dealership said that its a rare tranny,WTF? if thats true,then im doomed!!
