The 93 shifts in normal mode at full throttle at about 4300rpm or so and the 94 shifts at about 4800 or so. Is this right? or does this have something to do with the engines being difference. Since the 93 makes more of it'* power lower in the power band as opposed to the 94 being a tad bit higher. Any thoughts on this

ok so let me get this straight...the 93 shifts at 4300 and the 93 shifts and 4800...so where does this 94 come into play?

93 at 4300
94 at 4800
Sorry I was tired amd not typing well

94 and 95 shift the same.

My 95 USED to shift 500 rpm'* higher than the 93. They shift the same now due to the PCM in the 93.

The horesepower and torque curves changed when the 94 got the more efficient supercharger and throttle body.

Shifts are determined by the power curves, and programmed into the PCM. Transaxle is only doing as it'* told.

HOWEVER, the two trannies are not interchangeable without some connector wiring work. There are minor electrical differences.

Well i wasn't planning on tranny swapping. In fact the tranny is much better in the 93. I was just wondering why it seemed to shift later. Maybe it was because the car was faster and couldn't shift fast enough. I really doubt that but I just wanted to make sure since the torque curves of these 2 engines are different.

It'* PROGRAMMED to shift later by DESIGN. It'* not that it takes longer or quicker, or anything. It'* TOLD to do that.
