I have 69K on it now. I bought the truck @ 20k and from this group learned that the trans is the weak link. I immediately got a hayden cooler for it and ran it in series with the radiator. I go from trans to radiator to cooler back to trans. Maybe I did it backwards? Anyways, I have had 2 valve body issues (P1870 IIRC) and luckily they were both fixed under warranty. I am now getting a hard 1-2 shift again (no code yet) but since the truck is out of warranty, I am going to replace the trans with a beefier unit. Btw, my truck is bone stock, I never tow and it's fairly well babied. Other than the trans and the slip yoke bump-klunk I have had no problems.

</pre> <blockquote type="cite"> <pre wrap="">Brian,
I did a google search on the 4l60e and read an article that said Chevy designed the 4l60e transmission well but to save money it has mediocre parts from the factory. Several companies sell beefed up models. I guess we'll see how long it lasts.
Karl </pre> </blockquote> <pre wrap=""> A little bit of knowledge is dangerous. The 4L60e is nothing more than a electronically controlled 700R4. Nothing cheap about the design. Where is gets a bad reputatation is from people lifting them (the trucks) and/or installing oversized tires on them without proper axle ratios and this overworks the tranny and keeps it on converter stall a lot which makes a lot of extra heat and heat is any automatic trannies worst enemy. If your 4L60 is properly geared for its loads, properly cooled and service regulalrly with a fluid change and filter(not at GM's long recomemand intervals) it will have a long service life. The after market kits/rebuilds spoken of can beef a 700R4/4L60 to handle more than 700HP. One of the biggest mistakes people make is shift kits in stock trannies because the intermediate sprags are not that strong (they will last fine with stock shifting) and a hard shift kit hammer the sprags into a early grave. You are not saving anything with shift kits regardless of claims otherwise. In late 2005 GM upgraded the sprags in the 4L60. I have 700R4 (which the 4L60 is based on and share all parts with except valve body) in a 89 4x4 burb that has over 180K miles on it and tranny still works flawlessly. It has had regular fluid changes and a small aux cooler since day one. (even though it had a HD factory tow package) GM has worked to make 4L60 shift even smoother particulailty the converter clutch so it is no surprize that you may not feel it especailly if you have a stock 3.21 or 3.42 axle ratio which is really to tall to begin with in a heavy 4x4 with factory 31 inch tires too. ----------------- TheSnoMan.com </pre> </blockquote> <pre wrap=""><!----> </pre> </blockquote> </body> </html>
