th350 to 4l60e '76 c10
Is there an adapter needed? Has anyone done the swap successfully? All of my searches have turned up with the op getting redirected to a 700r4 or keeping the th350. I came across the kit below but can't find anyone to tell me if they have used the kit or a crankshaft spacer or??

The TH350 to 4L60 E swap is the same as a TH700R4/4L60 swap. There are small differences the 4L60E is a computer controlled transmission so a computer and TPS source are needed. Both need cross member relocation and drive shaft shortened. The 4L60E transmission needs to be off a standard SB motor, LS1 style trans and converter are different. The computer version is easier to program to you driving style if you use the TCI controller.
The TH700R4/4L60 trans has to have a TV cable properly hooked up and a Torque Converter Clutch lock up kit installed. No crankshaft spacer needed. You can PM me if you need additional information. |

With the proper transmission and converter None of that adapter kit is needed. It is for a LS1 style transmission on a 1986 of later SB Chevy non LS1 motor.

What engine did the 2002 Transmission come off of?
Can you post a picture of the input shaft? |

I know it was a 5.3 and the trans is a 2002 service replacement unit. Looks like the bolt pattern will line up.
