Transmission Problem? Weird shift patterns... Help!

[Steve98GTP]

Hello all,

As the weather got colder up here i noticed a few problems with my transmission. Initially, it has trouble shifting from 2nd-3rd under low throttle - typically this happens when i'm rolling along at about 60km/hr and giving it just a little bit of gas. The car will quickly jump in RPM's a couple hundred and it seems like there is not enough trans pressure to complete the shift.

The other issue i have is when driving full thottle, the car cannot make the 3rd to 4th shift (It seems to be unable to make the shift when approaching redline). Under lower RPM i can get into 4th gear no problem. EDIT: Could possibly be the 2nd-3rd shift again. The shift occurs when driving WOT at about ~150km/hr.

Anyone have any insight into these problems? Aside from these issues it shifts firmly and behaves normally. They seem to have come with the cold weather.

Thanks

I am having similiar problems but I do not yet know what it is, so I am of no help now. I will get back on here when I find something out. What year is your vehicle?

1998. How about you? Please do pass on any information you can find, who knows.. maybe we will discover a cheap fix! (Although i am fearing a tranny rebuild might be in our futures...)

For what it's worth, i am driving the vehicle in 2nd gear in the city right now and when i am on the highway i throw it into drive (From 2nd) when the RPM's get up at about 80 km/hr while applying no throttle.. this helps me avoid the nasty 2-3rd shift entirely.

take a look at 4T65E Transmission Info and see if your problem is there.
