Re: What is the best mod for quick 1/4 mile times?
If you have a '95 I know you do not have an AOD. '94 and '95 SC's have the 4R70W. From what I understand 4R70 is sort of an industry wide generic term for a 4 speed automatic, the W indicates Wide ratio gearset. The wide ratio gearset is the majority of the difference between this trans and the AODE. I am not sure of the gear ratios, but 1st gear is deeper than the AODE, and I think overdrive may be a little different also.
If you really want to convince yourself you do not have an AOD look for two things. 1. is there a T.V. cable, or third cable attached to your throttle body? I bet you have an opening in the bracket with no cable there. 2. Do you have an Overdrive lockout switch on the side of the shifter? This is only on Electronic transmission cars, the AOD is not electronically controlled.
