Excuse me if I missed a thread like this, but I thought it would be helpful to people doing 3.5 swaps on their cars if there was a thread where members listed the problems and how they where fixed or asked questions about problems they may be having with their swap... like me for instance just swapped a 3.5 in my car and it was actually happy4444's motor and tranny which is a 2000 lsd 5 spd with a built 3.5 and when I'm just coasting it almost acts like the clutch disengages and when I push the gas it feels like it catches and then goes fine from there, also when I'm at about 2500rpms and go to WOT it stutters up till about 4000rpms and the other day I decided to give it WOT from second gear and shifted into third and let the clutch out and it just stayed at 4000rpms but didn't sound like 4000rpms I almost didnt hear anything, so I pushed the clutch back in and it dropped to about 500rpms and drove fine after that (it idles at roughly 1100rpms).. does anyone have any ideas or suggestions I haven't gotten the codes read again yet since it was first installed.

 

Start with the codes and work from there.
