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.

2. When driving afteer few minutes it sounds and feels like its in neatural. So i put in 3 and gets most the power back around 3000 rpm. No idea what this is.

Fluid smells good. Up to level. Few weeks ago when i had that 1 gear problem i thought tps. I have codes but can't get reader untill later in week.

Does this sound like tourqe conv circuit? I bet that's one of the codes. Sorry for bad typin. Doing thus on small keypad

I just did that to make life easier for those trying to help you. Weird you got 2 codes meaning opposite things for the same circuit, might mean the tcc solenoid is intermittently sticking in either position. I don't think a wire fault could possibly cause both.
