Early model Transmissions.
- Thread starter Red91NSexy
- Start date
On what facts did he base this on ?
The 5 speed transmission does have wider gears that can handle higher HP/torque levels than the narrower-toothed 6 speed transmission.
For anything under 400whp, either should be fine.

i dont really know. the guy said "hey nice car. i am going to get one soon but it will have to be an earlier model because they have stronger transmissions." but thats good because mine is a 91 lol!:biggrin:
Its all good unless you have one in the snap ring range
how do i tell that?
where is the transmission code found?
It is explained in the TSB but the short version is that if you look down on the trans housing, just to the right of the airbox assembly you should see the number.
ok. thanks. hopefully i dont have one of those. i have almost 198,500 miles on the car. so one would think that if it came from the factory with one that it may have been replaced before it got it at 170,000 miles. (i hope)
That's not very reassuring logic. Just go ahead and check the trans serial number.
Like the guys have said before unless its snap ring range 5spd is twin disc clutch, the 6Spd has a single disc clutch has been more refined over the years shorter gearing, double syncroed etc. Lot of guys upgrade their old 5spds to new 6spds.

Just because a trans is in the snap ring range doesn't mean that it will fail but rather it is more likely to.
If you car has that many miles on it and it hasn't had any problems, there is a good chance it won't.
Mine is right in the middle of the range and have never had any of the symptons of it failing. I won't worry about it till it happens or I try and sell it.

trust me i am going to check first chance it get. but i cant afford to replace anything to expencive right now. so hopefully i will be ok for awhile
Lots of guys also upgrade the gearing to Short Gears and the 4.23 R&P.
Understood.
Yes I missed that one... was once there myself my old 91 car has a UK Type-R trans in it with short gears apparantly from factory. 4.23 R&P is a great upgrade for the 5Spd :smile:
IMO there is rarely a case where the US gear stack is beneficial.
