Need transmission help

[diacnik]

I have a 2006 Silverado that is having some tranny problems. Anyone have recommendations for a good shop, preferably in Henry County?
We just bought the truck, and it has been lifted and larger than stock wheel/ tires put on - could that be part of the problem?

Have you checked the fluid level hot in park white running?
What exactly is it doing?

The 4L60E transmission is good. If you don't put on aftermarket cooling it will die. I had a 93 suburban that ate a transmission every 5 years before I figured it out. Stock chevys just aren't set up to keep your transmission cool over the long term.

The ideal range for fluid temperature is between 175 and 225 degrees, and every 20 degree drop in fluid temperature can help to double the life of your transmission.

To say it another way if your transmission goes over 225 it will half the life of your transmission.

With my last overhaul I had aftermarket transmission coolers installed and extra deep (2 quarts extra), finned transmission pan tapped for 1/4 NPT pipe threads. So I could run a FRANTZ toilet paper oil filter.

More fluid quantity = less time the fluid spends inside transmission getting hot. The additional transmission cooler helps get rid of the heat. None or that matters if you don't have a clue how hot your transmission is.

A normally open thermal snap switch set at 225 degrees can be set up to give you an idiot light when you have reached that temperature.

I've heard good things about C&C transmission in Jenkinsburg, though I've never used them. You haven’t described what the transmission is doing, but you are correct that substantially larger tires can affect things, mainly as @Rocky says because of the additional heat generated by working harder. This is especially true if the axles weren't re-geared to compensate.

Stay away from c&c had issues with them and many others has also.

You may get away with a transmission service, new fluid and filter. If it that does the trick, then add a high volume pan and aftermarket cooler.

If it needs a rebuild, any shop is going to pitch you on upgraded internals, which is a good Idea. You should still add the high volume pan and aftermarket cooler.

Local shop up here does 4l60e for like 1250, but in town they want 3500. Be sure to go with the standard upgraded internals and i would highly suggest putting a transgo shift kit in it and larger transmission cooler/deeper pan (if you don't need the clearance off road). It will last a lot longer like that.

If you want to keep the truck for a long time upgrade it to a 4l80.

Ny last transmission came from https://www.godleytrans.net/. When I talked to them about Doing all the corvette shifter/transgo/upgrades. They talked me out of it. These guys build drag strip race transmissions
