I recently purchased a 2005 Buick Rainier that won’t go into 3rd gear (engine revs). It was run out of transmission fluid and I am assuming it burnt up the rear clutch pack.
Looking through car-part I see that the 4L60E has a lot of interchange options.
The transmission is available from another 05 Rainier, but I have to drive 100 miles to get it.
THE QUESTION
Is there a compelling reason to go with the Buick specific transmission or is it OK to get a unit from the interchange list?
This is a rather simple question that can’t be answered by just anyone. I appreciate any help offered
The 4L60-E was used in many RWD GM cars and all of their RWD small trucks in the 1990s and 2000s including Silverados, Suburbans, Yukons, and Tahoes. There should be a ton of them available.
The 4L60E for a Rainer is the same one used in Chevy Trailblazer, GMC Envoy , Olds Bravada , and the Izuzu Ascender . All are the same vehicle with just different front and back ends .
Thanks all, I think I got my answer (not to worry about interchange differences, if they exist)
The transmissions on these vehicles (Trailblazer/Envoy/Rainier) are easy to tear out/slap together… its not like working on a subcompact where everything is super tight. I can get a used 4L60E transmission with 120K miles in my area for $500. A certified rebuilt transmission is roughly $3000 plus $1400 install.
That means, since I am doing my own work, I can replace the unit a few times with no worries.
Heck, I can rebuild the original for about $300 and I have a backup waiting, just in case.
It’s a bit higher risk, but I’m OK with the possible outcomes.
