Offered for sale is a fully loaded two door GT that is very clean. Car runs and drives great and has been well maintained. Get 28mpg highway and 19 mpg average with this traction control equiped car. The four wheel independent suspendsion gives this GT a great ride, while the high performance tires hold the corners with ease. I am selling the Grand Prix because I needed a truck. The only problem is the transmission hesitates coming out of overdrive on occassion. The engine speed varies from 2K-3K rpm for a second than shifts to the correct gear. I simply give it a bit more gas and it find the correct gear with no problem. There is no slipping, nor does it make any noises, just a little slow coming out of overdrive lockup. I still drive it 50 miles to work and have even taken it for road trips to Maine with no problems. Price $2800, OBO.

What i am asking is, wtf is wrong with this tranny and if i do go the route of replacing it, would it be better to get a ht65-hd in there for added strength of differential (as i think the rest is the same)? thanks, and btw im new here
