I have a transmission problem its a bit drawn out but I have to explain. Just bought this 99 grand prix gt v6 3.8l, the guy said he'd dropped an engine with 80,000 miles in it. Which is great the engine sounds beautiful but this might be my problem. The engine was from a 97 grand prix I believe. I know he said 97. Tomorrow I will search the engine and find out for sure. I noticed after driving it awhile it shifted hard going up-shift and down-shift. I'm hoping it's just trash and a new filter and fluid will fix it, but I was searching on eBay for transmissions in case I need one and according to that the 97 engine is not compatible with the 99 transmission. Tonight it got stuck in 2nd gear for about 2 blocks at least and finally kicked into third and drove fine the rest of the way other than the hard shifting. So I need to know a few things. 1) is this 97 engine really not compatible with the 99 trans and is it even possible that it would still work just not work right? 2) do I need to get the 97 trans or another compatible trans and if so will I need to replace anything on the engine side that might have been damaged from this?
have the same problem?
