2012 Yukon Denali leaking slip yoke

Gurrzt · May 22, 2012

Does anyone happen to know the TSB for the front yoke (2wd) leaking transmission fluid?

Thanks in advance.

the dealer has it when you take it in ????

remember it may or may NOT apply to your truck

Sometimes it's nice knowing the number before you goto the dealer. It saves them time having to look it up. I know I have done it 2 times now and have been thanked by the service advisor for bringing him the info.

Yes, I understand this, I would like to read the bulliten before the service is performed. You are correct, it may not apply just for the trucks.

Subscribe to alldata. It's cheap and you get access to TSBs, manuals, etc.

Thank you all for the input, I received my vechicle yesterday late afternoon from the dealer, and even though I still do not know the TSB number, the dealer replaced the slip yoke with the following parts:

15926348-Slip Yoke

89059111-U Joint kit

The entire repair was covered under the 5 yr./100k warrenty. The dealer claims this is an updated part, with a stonger U joint, he also stated that it would stop any "clunking" when the vehicle shifts, or on acceleration (I have never had this happen anyway).

Hope this solves the problem, nothing like fresh transmission oil on a new paver driveway (lol)
