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.

The trans is a 2002 4l60e and I am mating it to a 99 sbc.

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.
