I've driven several 1997 F150's and they all shifted painfully slow under full throttle.
Anybody tried this kit? or have any other experiences with fixing this?

 

I had this kit on a 97 F150 4.6. I was very happy with the results up until the EPC solenoid fried, but I had 132000 miles on it at the time. I had installed the kit at about 5000 miles, so perhaps I'd gotten my money's worth.

 

Ordered it yesterday...can't wait. Almost too good to be true...$40.00 for a shift kit and you don't even have to drop the pan? I'm there! Thanks!

 

I don't know about those, but the Ford dealer tranny expert says go with transgo for shift kits, says the B&M eats up 4R70W trannies.

I'm going to drill my valve body and change some accumulator springs around.
