I needed to re-read the OP. Duh

2002 and prior 4t65e are much more inter-changeable than 2003-2005 ish

2006-2011 is its own breed

you CAN make a 2003 work in a 1999 but honestly youd rather just swap the entire pcm and stuff from a 2003 to the 99 lesabre since its an older model design... lots of work, little pay off, but thats my opininion Lol. It Can be done, just involves swapping parts and making it kosher for the 1999 pcm

this is after i wiped a ball of needle bearings and debris out of it. After.

Dont be like my trans. this is cv axle and wheel bearing damage from an oops

RECOMMEND THIS PART BIG TIME.

see the hose that popped off the tube a tiny bit? Yeah.

this is a wheel bearing , it still worked, and the car still moved.

You are resurrecting the dead here.

This is insane, I saw the thread I initially clicked in the recent threads. Perhaps it scrolled into a "different" thread? I know im not insane but I saw january 2022 replies. Im sane I tell you!!!!!!


Ive become the very thing I swore to destroy

A for affort?

The thread about the 99 and the 2003 lesabre/bonneville, can my post be moved to that thread or would I have to redo everything

Now now it'* ok. We all have those moments.
