1997 K1500; swapping to a 4L65E transmission
I have a 1997 Chevy K1500, L31 engine. That is a second Gen small block engine. It currently has the original one piece case, 4WD 4L60E. I have the opportunity to acquire a nicely built 4L65E from a friend for a good price. I know i will need a few things for the swap. I have been doing a lot of reading and research and I am having a hard time finding anything definitive. I saw a lot of good information on this forum, and LS1tech was also recommended by my friend.
It is my understanding that the electronics and the electrical connector are the same. I did see one thing that suggested that it was possible that I have a 12 pin connector that lacks a ground wire that the 13 pin connectors have.
It is also my understanding that there is a spacing difference between 2nd gen and 3rd gen engines and i will need to put a 97-98 bell housing on the 65E to account for the spacing difference. Is that true? is it that simple?
Will the GM92 torque converter that is included with the 65E work for my truck? It is my understanding that my truck is PWM. I also need a new TC.
The 65E started life as a 4wd trans, and my friend converted it to 2WD for a project that never was finished. I will need to have it switched back to 4WD.
Am i missing anything? Will this trans work in my truck?
