Different options how??? My trans I just put in this year came out of a Park Ave? Works just fine?

Will: If you put in a trans with the wrong final drive ratio, the trans won't shift cvorrectly because of the PCM???? Correct??

Now would you be able to Swap PCM'* or chips or whatever from the same vehicle that you got the different tranny from, would it shift correctly and work? Or be a waste of time?

For?????

Was it the Park Av Ultra?

Well, I just got back from a drive. I am very worried. My HUD works, it now will shift into first, but RPMS seem to stay at 5k and it doesnt pull hard at all, then second it pulls really hard like usual. I hope my transmission is not going out already!!!!

And yes, I was told that it was the Ultra, the receipt says it too. Is there any way I can check the tranny though to see if it is really the HD version or not?

There are no external markings dictating HD. The only way to know on a 4T60E is by the final drive ratio. If it'* 2.97, it'* HD.

Alright, anyone else wanna help out and tell me what rpm your car is at when your torque converter is locked at 50 mph? If you had an L67 that would be most helpful.

Not nessesarly. The 93 Olds 88 LSS all came with the 2.97 gearing and none were */C. Both non */C and */C Touring Sedans had the 2.97, however, the */C had the HD version. I believe that 92-95 3800 Regals also had the 2.97.
