Transmission? 2006 Chevy Uplander, minor reving, infrequent/random "shudder"

[Ban Bot]

I am assuming this is a transmission issue.

What should I be looking in a shop to get this diagnosed? Where to go / where to avoid? I live north of Seattle near the King County/Snohomish County board (Shoreline/Lynnwood).

In the last couple weeks the van has "reved up" a little before shifting. Didn't think much of it. Yesterday I got a shuttering clunk once, felt like I went over a small patch of rough road/pot hole. That had me more concerned. Today it did this 4 or 5 times in my hour commute.

I assume I need to get this checked out ASAP. I have heard bad stories about transmission shops but of my friends with the bad stories couldn't really advise a good place.

My pocket book is already crying hahaha 'Tis life. Thanks for any feedback and advise.

Have you checked the trans. fluid level yet? It'd be the first thing I'd do. Cheap and easy.


Second, as an aside, shudder is the word I think you were looking for. Shutters are used on houses to cover the windows, like storm shutters.

Yeah, I'd check the fluid level, and if it hasn't been serviced, I'd do the transmission fluid/filter.

 

[Ban Bot]

Thanks--will check that today.

Levels checked, looked good.

Van has 88,xxx miles; transmission serviced at 75,000.

did they do a power flush or a drain and fill when they serviced it?

Thread about possible solutions.

Poster John seems to have had to get the trans repaired:

We picked up our 2006 Uplander with the transmission slip from the dealer last night and here's what was on the labor & parts form: Reconditioned trans, replaced forward band, both sprags, pressure control, solenoid and flushed cooler.

After nearly 400 miles since having the work of reconditioned trans, replacement of forward band, both sprags, pressure control, solenoid and flushed cooler, and we have not encountered any of the slippage that went on over the past 2 1/2 years. This has been by far the longest duration without an issue concerning the trans slip.
I hope our frustrations are over and it's smooth sailing.
I'll write another update 400 miles from now.
