Hi gents, 98 gtp xp, ssic, ported heads, 2.9 etc. Tranny has a zzp shift kit in it. My car has never really had a very hard 1-2 shift, even when I took out all tm and jacked up the line pressure's and lowered the commanded shift speed. I put a shift kit in it but that really didn't do to much except made a stronger part throttle shift. I'v done the fluid and filter twice in the last year. It didn't smell burnt and there was no material laying in the pan. Now the problem is on a wot 1-2 shift the tranny will start it's shift at 6100 but will not finish till ~6500. Sometimes like last night it seems like it starts the shift but just slips alot making me back off the throttle to shift. 2-3 is good. Thanks for your replies.(trannyman)
