Talk:GM 4L80-E transmission

Information on 4l80e Automatic Transmissions. Please be advised that I changed the "4L80E Transmission" wiki page as to what date this transmission was available as an option on C/K Pickups. I have a 1993 Chevy 4 x 4 with the 7.4L (454 Cu.In.) engine, a "2500 HD". The option sticker in the glove box shows option "MT1"...a 4L80E Transmission. Also: The "GM Transmission" wiki page shows this model of Transmission (4L80E) as being available as an option as far back as 1991. I assume it was 1991 that this model of transmission was available.I base that on the "GM Transmission wiki" page. Admittedly,the info. on that page could also possibly be wrong. However, I am positive that my truck, a 1993 model, does indeed have option "MT1", a 4L80E.

Yes. I have a 1991 R2500 Suburban with a 6.2L diesel and a 4L80E transmission. They happen. — Preceding unsigned comment added by 76.20.228.11 (talk) 23:44, 18 July 2011 (UTC)

Error in Torque rating on page
the 4L80-E is good for a bit more FtLbs than you stated.

Conversion for 4L 60 to 4L 80 E
04 Chevy Silverado, 5.3 2 Wheel Dr. I have a 99 or 2000 4L 80 E transmission out of an old Penske truck the fluid lines are put real close togather. So I believe it is a older style trans. There wasn’t a torque converter with it. I found a stock one out of an old 4l80e ! what torque converter is recommended. The 5.3L it is freshly rebuilt, turbo, injectors, cam fuel pump intake valve springs have all been upgraded 174.250.210.82 (talk) 02:54, 4 October 2022 (UTC)
