Good Morning Gurus! I'm new to the board but have been using it as a resource (Great One at that).
Quick Facts:
-2012 GMC Yukon Denali 152,000K miles
-Bought Brand New
- 0 problems to date
ISSSUE: I was running fine last week, felt something a LITTLE sketchy when shifting out of first (at a stop light).
Next day was driving on the freeway (AND ZOOOMMMM) RPMS hit 3,000 + and I'm doing 30 mph until I can get to the closest town.
After I set for awhile I was able to drive with little problems; HOWEVER, the engine light came on AND has sense turned off.
My question: I've been to one mechanic who had good reviews. He didn't even look at it and just said "yeah, I know what's going on $3300 for aftermarket parts and a rebuilt transmission".
I gather he knows his stuff; however, how do I know what's actually gone in that transmission? Seems to me like a Torque Converter would be necessary and whatever else. Also, he would be using Sonnax aftermarket parts? **Opinions here?***
Is this just a "fix it once and replace everything while you're in there approach" and is it advised?
I believe I will be needing work done to my Catalytic convertor and likely some suspension repairs in the near future.
Trying to figure out my total cost of ownership or if its time to abandon ship and move onto the next problem vehicle.
Any advice is appreciated - My apologies for the long post.
