bored me to death

I have a twin turbo 4wd Silverado 6.0L with the 4L65E making 940hp.... 5 years strong... transmission is perfect. I just don't start it up or drive it.... Will last me forever

[@Samstah]

Why are all these companies rating there transmissions on HP? Transmissions break because of torque.

So glad I went with a 80e with a shift kit on my build after watching this

Great video! I had to give a big sigh of relief after watching this video! I'm getting ready to LS Swap my 75 Chevy Caprice Classic! Just bought an LQ9/4L80E Combo! Gonna beef the motor up a bit more but now I feel more at ease... Big shout out to the Driveway Engineer! I'm addicted to your videos! 👍

Thanks for sharing and also for saving me a lot of money to rebuild my 4l60e. Ill go pick up an 80e over the winter.

Literally every junk yard has some trashed trucks with 4L80E’s. Get one and rebuild it or have it rebuilt

I removed the THM375 (THM400 with longer tailshaft) in my 1990 454SS Truck. I built a 4L80E with heavy parts and installed in my truck. I used a Compushift electronic shifter. That was in 2006. Still running good. I installed a heavy duty cooler with fan for cooling up front.

I wanna thank you for sharing you knowledge

[@EGGINFOOLS]

I blew apart a 4l60e on my supercharged 98 S-10 SS 4.3 making 470whp @ 30k. I also sheared the output shaft on my tune only 4.8 RCSB 4x4 Sierra with 33s. This video is all kinds of good advice.

Thanks for the lesson teacher, good stuff ,

I have a turbo 400 in my four wheel drive 2500 flatbed that I work and he does a great job almost completely indestructible

Hi JR, great video, wish you would have discussed the difference in 1st gear between teh 4L80 and 60E. Appreciate the upload!

[@marcstlaurent3719]

I have a 5000 pound Blazer with a twin turbo 555 BBC that makes 1340 to the wheels and a built 4L80E works great , I don’t care that a 400 with a gear vendors which used to be in it is quicker down the track I like the 3000 ish lock up converter I have and being able to program the rpm I want it to shift it , I am using the ez tcu and have the hand held mounted permanently to display rpm, speed , whether converter locked , voltage, tranny temp , tps percentage , gear it’s in , and the bonus of having a manual mode where I have a toggle switch to shift it just like a manual valve body .

[@kyore789]

I was gonna keep the 60 in my swap but I’m glad you opened my eyes.

[@yahawashitheserpentofbrass2140]

Great info..I’ll head to the yard for a 4l80e

[@kennethwalker4551]

Thank you for the information I really didn't want to hear. I just dropped almost 2k on building a 4L65 that can't even stand up to my mild 5.3. I guess you never get too old to get schooled. Now to find a Turbo 400 or a Tremec TKO

[@surfertube44]

Got a 2000 Gmc 3500 work truck and not a dully ,owned since new and just keeping it tuned and full of fresh oils keeps me running down the freeway at 80 mpg with 6000 pound of load comfortable ride with 30 2X4 studs on the lumber rack and a 4L80E Allison tranny included!

[@mikegee8900]

I just picked up a 6.0 yesterday and been looking for a 4l80e I was wondering about the years.. you answered my question. Thank you

[@gunnermitchell7339]

Would love to hear your thoughts on the best transmission to use on a 4x4! Love all the vids, you seem like the most honest and knowledgable guy I have listened to on KZbin.
