8 work days to replace clutch??

no not the norm. should take 2 days tops including getting parts

 

$12000 seems extreme to me . 2 to three day with getting parts .

 

seems pretty high to me, normally the flywheels can just be re-surfaced though not sure what a new one runs.

i had a clutch put in at a dealer was done in 2 days and they didn't pull the truck in till the eve of the first day. did new rear main seal input shaft cross shaft all new linkage resurfaced flywheel new carrier bearing and a couple new u joints replaced a hood stop cable and some other little things and the total bill was less than 6k

 

Nope. Way too much. I just had my clutch replaced last month, rear engine seal, flywheel machined, and new brake installed. CVIP done, steering shaft u joint and yoke replaced, air dryer cartridge replaced, in dash park brake valve removed and replaced, and a couple of lights fixed. Total $3600. When I remove the costs not associated with the clutch, the clutch part comes to about 10 hrs labor (1100 ) and around 15-1600 for the clutch, flywheel, etc.
It sounds like these guys don't have a clue what their doing. Why are they replacing the flywheel housing? And could not the flywheel been machined (that cost 115 to do mine). I don't have a problem with someone learning as they work on my truck provided that 1: they have somebody with experience and know how to supervise them to make sure it's done right, and 2: you only get charged what it would take an efficient shop to do the job, not get billed for somebody's on the job learning process. I suppose at this point it's not practical to get your truck out of their hands. But I would be asking them some hard questions if it was me. Good luck.

 

Curious as to why they want to replace the flywheel housing and bellhousing? And they should be able to resurface the flywheel, provided it isn't worn in too much.
