Well to give you guys a little history of the truck its a 1999 2500 4x4 Quad cab with Edge e-z, Banks brake, 4" Turbo to tail magnaflow exhaust and a AFE Stage 1 with the PG7 filter. As far as the transmission goes it would shudder very badly going into overdrive so we took it to a very reputable aftermarket diesel performance transmission builder here in Denver and its been back twice for a few issues, i. e. exhaust brake and 4 wheel drive were inoperable. The second time we took it in was for excessive smoke at start up. They replaced the torque converter as they said it was too tight. Well a few weeks have passed and the truck has gotten to the point were even if plugged in over night or during the day for that matter that it wants to stall as soon as you drop it into drive. Even if you let the truck warm up in park it doesn't seem to be any better. The truck never did this with the factory transmission and has only done it since having the new transmission put in. So I'm hoping that all you guys and your wisdom can help me diagnose this issue.
Thanks in advance for the advice.
