Adapting a 4l60e to a NP203 is either installing the spacer or the shorter output shaft onto the 4l60e. Only one of those needs to be used, not both.

Then bolting up with a TH350/NP203 adapter.


A 27 spline input needs to be installed into the NP203 if it doesn’t have one already.

Keep in mind you will need a vss added to the np203 (this is something we do not offer) to keep the transmission shifting happily. If you are doing a doubler system we offer the service of adding a vss to the np205.

If you already have one of the items on this list and do not need to order just put a (0) in the quantity.
