When at WOT the trans wont shift into 3rd unless I let off/press the gas peddle, sometimes I have to peddle it a few times for it to shift. It wont manually shift into third if I up shift either. The trans shifts fine at all others times except WOT, nice firm shifts and when I peddle it to get it to shift it hits 3rd gear hard. The car was recently tuned, stock stall, 3.73 gears, 275/40/17 tires. Please help!!

I will continue searching the forum looking for some kind of direction to go. Guess the first place I go is the tuners tomorrow AM.

 

tuning does sound like the best move

 

thanks for the quick reply.
Could you give me any idea what he could have mis-programmed to cause thiscondition?

 

Possibly a tuning fix, but I doubt it. Tranny is more than likely going south... Start saving, it could last 20k miles of normal driving or could break the next time you mash the gas....

 

I would have to agree with blkws6 that it is probably more of an inturnal problem like the 3-4 clutch pack. If this started right after the tune you might get lucky. Vince

 

It may be the 3-4 pack but I usually try and give the less expensive things to check on first and with the recent tune its defiantly worth a look first

 

Seems it was the tune. I only did one run on it but it shifted nicely, where it wouldn't shift without problems before.

I was considering a shift kit but the mech said either tune or kit but not both. He mentioned that tuning was about as good as a kit, is this true or no? Also willa 3800 stall rush the demise of my tranny?

 

mine doing pretty much the same thing... define "tune" sorry im new to this

 

Good to hear is always pays to look at the easy stuff first
