98. Gtp no mods 122k miles. Few weeks back my 1st gear sucked it shifted late but after first its gold. Now i think i have 2 probkems here.
1. Sometimes at a stop it stalls. I stop then when i let off brake it stalls. All the gears. Put in 1 and drives not stalling. I then shift up to d and all is fine. Sounds like tourqe converter prob? Also when car idles i have a nasty grinding sound. Can hear when it in 1-2 gear untill get at cruise speed. Those times wherr i have to start at 1 gear that noise is loud. Pretty sure these are related. I have a video of sound need to upload.
