That makes sense from what I've read so far.

Make sure they replace the transmission filter while they're in there.

Let us know when it's fixed,

 

Got the Blzr back Monday. It was fixed earlier but we were heaading on the oposite dirction to pick it up

Result was a contaminated switch on valve body.

Previous owner must have added some tranny conditioner and it disolved the gaskets and placed it on the swich causing it to stick. Much scraping and a few tries and it is now working.

The tranny shop has seen rust inside the xmsn from this stuff, claim it has a high acid content, so beware of snake oil

 

Glad you got it fixed!

 

Excellent! I find that even if you need to take your truck to a shop that often, when they think you know something about it, you're less likely to be taken advantage of. Also, the more information you can supply, the easier the diagnosis, in most cases.
