LTX and LSXPutting LT1s, LS1s, and their variants into Third Gens is becoming more popular. This board is for those who are doing and have done the swaps so they can discuss all of their technical aspects including repairs, swap info, and performance upgrades.
OK I got a 95 lt1 out of a road master came with Trans and harness and pcm OK do u need a different mount for the Trans than my 700r4 can I make a standalone harness I found a page on how to make a stand alone will it work and can I use my stock radiator
Trans is basically a 700R4 but electronic shift controlled by the ECM. Mount would be the same. Radiator will work and yes you can make a stand alone harness using the LT1 ECM and harness. You may need to modify the radiator but shouldn't be anything major. Maybe someone will chime in with a more definitive answer. HTH!
Almost forgot, you will need to do something for the torque arm as your 700R4 has the torque arm mounted to the tail shaft. You can get a trans mount with provision for torque arm mounting or you may be able to swap the tail shaft from your 700R4 to the 4L60E. I believe it to be a direct swap.

Reason: added info about torque arm.
