Hi new here so please be pashant
Ok here is my problem I have LS1 and 4L60e MS3 and MShift 5.102 Finally got the Mshift to work had an issue with VVS was a poor sensor. Drove home from work let the truck stand for a few hours. Changed a few settings in Mshift nothing mager . Started and drove down the road and it would not shift out of 1st. Pluged laptop in noticed the current gear at -1 eg Reves regardless of position of the shiftier.
Tests carried out so far.
checked the loom from amp seal to plug on box continuity ect ok
removed the transmission pan checked wiring and swapped pressure switch manifold. Still the same I then removed the Mshift and tested in my trans sim and noticed that if I lower the oil temp below 55c the current gear would jump from any gear to -1. So I put the Mshift back in the truck and it went straight to -1. If I heat up the temp sensor with a heat gun to about 80c it then gose to 0 on the current gear display. Have reloaded the s19 and ini still no joy,
Any help would be graitlly appreciated
Cheers
