Does that trans have kick down or TV throttle valve cable linkage? On an operational note, the 4L60e's are computer controlled and don't use a vacuum module or a throttle valve cable to kick down like the 700R or 2004R's do.

It is either a computer controller issue of a problem inside the transmission itself. If i was facing this, I would change the fluid and filter, and then swap in an aftermarket stand-alone controller in. They are not cheap, but you get what you pay for. Here's one example. https://www.usshift.com/usq4.shtmlIf there are still problems with the shifting, you may want to have your transmission rebuilt by a quality transmission shop who specializes in 4L60's or just buy another transmission outright. Trying to order and swap in a valve body in the car may help, but it may not either. Such is the nature of our hobby.

I was able to test the function while driving the car . Rigged up a couple of volt meters at the transmission harness plug and watched them going down the road . The problem is in the tranny . Just wasn’t sure if there was something else other than the valve body to consider. I’ve talked to a couple of shops , they just say replace the valve Body .

You can check out this link to find both upgraded hard parts, shift kits and technical info on setting up and improving the 4L60. With 50k miles on it, it might be prudent to freshen the entire transmission if you are going to be in there. https://www.sonnax.com/gm_4l60e

Could be a wiring problem from the trans connector to the solenoids or speed sensors.Are you able to rig something up to get codes?

Meaning in drive or overdrive it works perfectly. No I don’t think it’s that smart . It just has a stand alone controller .

I get it that changing to a different TCM is an expensive part to throw at the problem. 4L60's have their own inherent weaknesses, but they can be overcome with aftermarket parts including that goofy 3.06 to 1 first gear ratio.

I can't for the life of me understand why on earth someone would choose THAT transmission to retrofit into ANYTHING! They are one of the worst transmissions ever, I run a mopar specialty shop and still end up replacing more 4l60E transmissions than all others COMBINED!

Pretty much what I was thinkin I'm curious to hear your input regarding a list of the main points of failure in the 4L60's that have met their demise in your shop? Is it generally just burned up clutches and bands or are the failures randomly spread throughout the transmission guts? Thanks in advance.

Solinoids, sensors, the sun shell breaks (we upgrade em all to "the beast"), clutches burn up mostly 4th gear but all of em are suceptible, the valve body spacer plate wears out so the check balls don't completly seal off and sometimes they get stuck in the plate or blow all the way thru.

Pretty much what I was thinkin This is a response I would have expected from the facebook crowd. Responses here are typically intelligent and thoughtful. Yours is neither. Never once in my post did I ask for an opinion on the quality of the transmission. In the future if you don’t have anything constructive, just keep scrolling. Or head over to Facebook. You’ll fit right in .
