H3 2008 , weird Tranny slippage

[Simplelife]

Hey y'all , I'm new to the h3 ( it's my wife vehicle ) and all is awesome on it , we love it . Just one thing today went crazy... So after about 1 hour of driving it wouldn't shift into 3rd felt like it was slipping , so I pulled over and put the gear in park then back in drive and it worked perfect !?! I'm just confused if it's a Tranny in the way out or a solenoid !? Fluid was a quart low this morning so I added a quart following the manuals instructions on how to check the oil level ... It's been working good since.. Any ideas what could cause this ?

Worn out fluid could be a cause. How many miles on the transmission and/or fluid

That could be the case, it looked a little old .. We barely bought it a week ago . Has 122k miles .. We drove it for awhile and hasn't happened.. Must be worn out oil .. I'll change it this weekend ... What do y'all suggest just drain from pan and change filter and fill ?

Pull the pan, drill it and weld in a drain plug (or a bolt in kit), change the filter and fill it back up. After getting it good and warm, drain the rest of the (almost) new fluid out and refill.

anyone know how much a dealer charges to drop the pain, new filter, fluid, and gasket?

edit: Just got quoted $339.

Sounds about right, quoting about 2 hours of labor and the rest materials. Not sure what the book rate is, but it takes about an hour to do. In other words, not surprised that they are quoting 2 but it is less. Any good independent transmission shops in the area?

It's $300 + tax in my area. I think it uses about $110 just in Dex6!

Thanks for all the replies guys.. This forum is as awesome as Cummins forum ... I haven't yet changed the tranny fluid but, this weekend I am .. And going to do the transfer case as well.. I see there's s bunch of debate on weather to use dex VI or manual t oil ... My manual says to use manual oil, but I see there's no reason to use that type of oil in the transfer case .. So I'm going to go with dex....
