Yesterday I finally opened her up and I noticed that between all gears there's about a .5 second delay between gears engaging at WOT. While in this delay, the car seems to "grab" into the next gear and jerks the car.

I've got a Transgo shift kit to put on, but will this fix the problem at WOT? At normal driving it shifts great.

Any other turbo autos have this happen?

hmm mine grabs pretty good in every gear. its just sluggish to downshift a little. i do have a transgo kit final drive and cooler on mine. i guess its just sluggish in general, but im used to driving a 5 speed though sooo.

my trans sort of freaks out under partial throttle accelearation. shifting, not shifting, it gets all confused.

at wot though it does pretty well. no real slippage at all.
