4l60e Transmission Longevity Good News I Hope

[bbwb]

2006 GMC Ext Cab...unlike the majority, my transmission crapped out at 61000; broken weld. Upgraded to heavy duty parts on the rebuild. Am at 84000 and shifting good (damn clunk on 2/3 upshift.

Wondering if this thread is still active? I have 187k on my 2005 Suburban, I'd love to say it's going strong but I've got a code: P0894. Which is for Transmission Component Slipping. To me just driving around town the vehicle seems fine occasionally it will shift hard. I've tried clearing the code and running some Lucas Fluid in the tranny, but it didn't help as the code came back. I've been researching this and it seems that in theory it could be as simple as a 30 dollar solenoid or as expensive as a rebuild (more or less). Most of the people who replaced the solenoids, changed fluid and filter..etc ended up getting a rebuild as that did not fix the issue. Transmission shop wants $650.00 to change out $30.00 part. So I'm considering a local rebuild for $1650.00. Anyone else run into this problem or have any advise?

4L60E with 268,000 rollin' 35's and ZERO issues! Flushed the Tranny at 200k. I don't know the exact history prior to 120k but it was obviously well maintained...

I did pan/filter service every 25-30k in my 2004 Silverado, had 185k on it when I sold it. Still doing fine. Once in a blue moon slip on starting off. I would say once every 1000 miles. I have 65k on my 2013 Silverado with the 4L60E. Just did my second pan/filter change. Do that service every 30k (DON'T DO FLUSHES) and I've had good luck.

Listen man, those two solenoids are so cheap from Advance Auto, and they are so easy to install. If you can drop the pan you can do those solenoids. Might as well give it a shot before spending any money. Hard shifting...that could indeed be the solenoids. Do yourself a favor and give it a shot. F those guys who want you to spend all that money.

I've got 170,000 on my 2003 Z71 4 x 4 extended cab. I bought the truck with 75,000 on it and did a fluid change right away, then every 50,000 after that. It still runs like the day I bought it. I'm selling that truck now because I just bought a 2013 to replace it. Let's hope this one is even better than the last one!

My 60 made it to 190k. 65k of that with a 6.0.

[WilliamBos]

217,000 on the trans in my 04, did one dealer flush, a pan drop/filter then a slow flush when my trans lines started leaking. New lines, bigger cooler, topped up and never had an issue, even towing.

Mine has 227000 on it, and i just replaced the Torque converter. Well I am about to. I plan on rebuilding the one that's in the truck and throwing another in that I just rebuilt for a guy which he never picked up. His was and 06 and had 170000 on it. If you change the fluid religously and drive easy, the 4l60e is a good transmission. Not bad to tow with, however for heavier stiff I would prefer the 4l80e.

 

From what I've seen and heard, these things have a life expectancy of about 150000km if you take into consideration the people that don't know how to maintain a vehicle or a transmission.

1999 GMC Sierra heavy half ton Z71 extended cab 5.3.. Have no clue which transmission is in it. Purchased the truck with 210 on it and it just turned 249.. Changed all oils when I purchased. Flushed the transmission and using synthetic with an recommended additive.  Been towing a boat that weight in the 2500 range to the keys and back and also a trailer that weight 8000 + gear, with no issues. I'm about to change the transmission oil again, but this time I see no need to flush the system. 

 

I read this threat cause, we're considering a long six month camping trip out west, and I"m wondering should I trust my current truck, motor and transmission, or should I purchase a newer truck.?

I have a 2001 silverado1500 and i got 306000 mi out of before its first rebuild.i beat the hell out of this transmission from racing to hauling.i changed the fluid and filter every 12mo on the dot.the 4L60e is the best transmission out there.

[Rosco]

2001 Yukon with 195,000 and a 2005 sierra z71 with 175,000. Both original and working great. Regular fluid and filter changes, Dexron VI or Mobil 1 fluid.

2002 5.3v8 w/ 3.73 gears w/ tow package.  My 4l60e lasted 155,000 miles and still had energy left in it, but I recently replaced it because I am towing a camper interstate pretty often and I could tell it was on it's last legs when pushed to the limits.

Im the only owner of veh and I pretty much babied it.
