4L80E Differences between Early and Late models

Curt is in the testing dept to 4L80E Differences between Early and Late models. He's using some 4L80E cores to show the external differences between the early and late models.
The early models with a year range of 1990-97 had coolant line fittings that are close to each other. Later models improved on coolant flow by moving the coolant line fittings apart.
The early model case does not have a top bolt hole which will bolt up to 5.7 to 350 engines. Later models featured a top bolt hole to bolt up to LS engines.
Early models also have a short linkage shaft and the NSS was in the shift console while the later 4l80's had a NSS on the transmission and a longer linkage shaft.

[@kodiakcopilot]

Damn it! My 1995 GMC dually has the cooler lines close together.

[@laqutis1119]

Those are still good lol

[@Sobriety5424]

kodiakcopilot it’ll be fine. Trust me unless you overload that fucker dead heavy daily you won’t have issues just keep everything taken care of and drain the fluid every 70k to 100k

[@colbyvittorio3704]

kodiakcopilot lol I was thinking the same thing 😂

[@mezee1703]

Are the flexplates all the same for the 4l80's? Thank you

[@jammy46235]

Hello love the channel question is there a difference in a 80 e and 60 e flex plates

[@MonsterTransmission]

Thanks! 4l80e normally is a 6 bolt while the 4l60e is a 3 bolt.

[@teehill4384]

I have the older version 4l80e with the lines close together it doesn't have the screw whole up to center but it has everything the newer ones have electronic wise will it be ok behind a 6.0 LS

[@miguelangelrivera36]

Are torque converter interchangeable??

[@bruniccoetzee6838]

Just what i needed. Where can i order or get the wiring diagram and do i need to open the transmission to do the wiring

[@MonsterTransmission]

Your local parts store should have a harness 4L80 transmission pigtail

[@YagersAutoBarn]

Will a late (2002ish) 411 pcm be able to control a 93 4l80e?

[@MonsterTransmission]

Yes it will. It will need to be re-pinned and flashed to 4l80e

[@chrismigl27]

I have a 70 Chevy 350 that will be using in a project and would like a 4l80e (for 4wd) can I use the later housing with the top bolt hole for have to seek the older one with the bad design on the return line? Thanks much

[@MonsterTransmission]

Since this will be a 4x4 Conversion we suggest you reach out to AdvancedAdapters.com at 800-305-2223 they specialize in all 4x4 conversions and will be able to set you up with perfect Adapter Kit. If you want to run the 4l80E you will also either need a Stand Alone controller like a Compushift controller I will send the link below or you can make it a Full Manual Valvebody which would be like a Stick shift with out the Clutch. Thank you for choosing Monster Transmissions.

[@autumnjeserich2689]

Are the pans interchangeable?

[@gabrielrosalesprieto9969]

will a early model 4l80 fit a 03 6.0?

[@cadipunk918]

Is there a wiring harness upgrade/retrofit for my 91 Dually? My 4l80e is losing speed sensor signal and going into 1st gear only. Thinking my wiring is messed up. Fluid is red and fresh. 116,k miles. Pulls great when it’s working right. You mentioned my wiring is no longer available.

[@MonsterTransmission]

Yes there is, the old harness is discontinued and updated with new pigtail it avail

[@Almeshtages3]
