Hey Folks.
Some may know me from the Handle and many dont. I am in no way new to K trucks but very new to this site. Should have joined years ago but never got around to it.
Reason for visit today was seeing what I could find on 4l80 swaps in the K5 and though I found some info I did not find anything along the lines of the swap I am doing.
I'm one of those guys that cant keep a transmission alive to save his life.(in this Blazer anyway) I've pulled the 700r4 with full manual Valve body and every goodie money can buy out of the blazer and now placed in one of the K10's to do this 4l80 swap.
So here is the swap. 4l80E that has been rebuilt with all the best clutches and is sporting transGo Full Manual Valve body. I kept the adapter that was between the 4l80 and np236 seeing how much shorter it was then the normal 208/241 adapter. I'm going to use the np241 with the 236 adapter. The 241 has SYE. All I had to was have the input on the 241 swapped out to match 32 spline of the 4l80.
So 4l80,236 adapter to 241 with sye. Only other change was to have Kert at Diy4X make me some engine side mounts at an 1 5/8 offset. With these changes the 4l80/241 fall back in same location as the 700r4/241 location. Though I did manage to clock the t-case down for this swap.
I found that I could use same cross-member. This swap is very simple and I am suprised its not been done more. And Keep in mind I have 14 inchs of lift.
I will post link to Photobucket Album for the Blazer as soon as site allows me.
