Good evening, I'm looking for measurements (length) for the different 4r70w/tc combos. Also, what adapters and crossmembers did you use?

4r/ D20
4r/ Atlas
4r/ np205

thanks

With D20 using Advance Adaptors the transmission/transfer case combo is 2 3/4" longer. Just long enough that there is an interference with the transfer case and body cross member if sticking with no body lift :mad:. I modified the transmission crossmember to lower the transfer case just enough to fit under. I dont like body lifts.

Which measurement do you need? Front of transmission to front of t-case? Or...? I'm running an AWD 4R70W using the OEM transmssion tail housing. Atlas bolted directly to that, no adapter. Made my own crossmember.
