2018 Venetian 37M

Two weeks ago had a Trans Com Failure on dash. Coach would not start. Had it towed to Freight liner dealer. Quoted me two hours of diagnostic at $193.00 @ hour. Advised the PDM needed to be replaced. They fixed the PDM, however, no communication to transmission to allow the coach to start. They requested additional 3 hours diagnostic. First estimate was $1935.00, after second diagnostic $ 3500.00 with no fix. Also total failure of jacks and two of three slides not working. Anybody else have these issues.

They're firing the
Parts cannon
Having NO IDEA what they are doing.
Get it to another shop as soon as you can.

I doubt there is even an inkling of an excuse for their misdiagnosis.

History says they'll keep doing this until you just give up...many many dollars from now.

Jacks and slides?
That's a junior-high-school type power jumper test.
