My 4x4, 4l80e is leaking ATF, sounds like it's a front seal. One shop told me 10 hrs/$1000 and it sounded high to me. What would you say is a fair price to drop tranny and replace seals? Thanks in advance.

Looks like you have a leaking torque converter seal on the transmission. Repair is mostly labor and should cost a couple of hours at whatever rate your shop charges. When replacing the engine, a new seal should be installed in the transmission but not many people think to do it.

Thank you for the reply. The shop that replaced my engine was a joke--I had spark plug wires burn through on the exhaust manifold, exhaust leaks, lower radiator hose blew off because they didn't tighten it. I will be using a different shop, I just needed to have an idea of what I'm looking at

Replacing the seal is the easy part and would take 30 minutes. Labor to remove and re install the transmission will be the majority of your bill. It wont be 2 hours.....guaranteed. On a used truck you can run into all kinds of issues. I wouldn't be surprised to see an 7 hour labor bill.

First shop I talked to said 10 hrs. That seemed rather excessive. If someone told me 7-8 that would make more sense

Did you get an estimate from a tranny shop? Reason I ask is because those do R&R's all day long and may quote you fewer labor hours than a bumper-to-bumper shop. Just a thought, but I'd definitely go grab 3 or so estimates minimum. It's a lot of labor, and different shops have different rates and will quote different hours.

Well it took me 2hrs to drop my trans and maybe 2 to 3hrs to put it back in recently. Literally took 2 mins to replace that seal once my trans was out also...i would hope a good tranny shop would be faster than my 4-5hrs to re-re a trans on my shop floor.

Just for reference, I just paid a trans shop $1k to drop my 60E, take out the guts, install guts in a new case, and reinstall. this is in my 4x4 2 door tahoe.


10 hours for your job seems a little excessive.
