I have a 4l60 in my monte and its drags when i push the gas in drive. It goes into reverse fine and pulls but not in drive. The fluide level is correct, i cant see what the problem is.

 

Check Engine Light on? Any codes such as P1870 for slippage? How many miles on the transmission?

I was told it was rebuilt a year ago. It came out of a 2002 truck that was totaled in a head on collision. I dont have the dash for the car right now but i do have the connection for obd2. I havent gotten it scanned yet tho. I just needed to know what could be a possible issue?

 

Put a pressure gauge on it and see where the line pressure is.

Unplug the harness to the transmission and see if you can move. Unplugging the harness will put it in limp mode and you will have reverse and 3rd only.

What gear is the selector in?

 

Ill try that when i get back to the shop tomorrow but it drags in all d 3 2 and 1.

 

Ok i unplugged the harness from the transmission and its still doing the same thing. I think it pulled a bit better. What does that mean?
