getting my facts together before ripping apart an auto shop, who has done a ZF6 cluch

Alright guys I just had a "AAA" rated shop change the clutch in my 7.3 and i am more than pissed off at the quality work.
My first sign of a problem was the brand new oil leak on the drive way so i crawled underneath to investigate and this is the first thing I see-



INSTANT RAGE

The bolt is cross-threaded and the cover is mangled

Now I understand this is not where my leak is coming from but it did show me the quality of work they do. I looked farther back and found fluid dripping from the bottom of the transmission and the main seal from the engine.

I have not done a clutch change before and my question is there- is there anything that can be disturbed that they caused to make the tranny and main seal leak during a clutch change? I want to get my ducks in a row before I take the truck to the shop and give them an *** kicking.

Its not the rear main.... at least very not likely... climb up on top and check the valley... stick your hand under the turbo... there is a drain that will run down inside the transmission case and look like a rear main

Like already stated your leak is probably from up top and leaking down the drain hole coming out near the inspection cover. There really isn't anything to damage which will cause a leak while doing the clutch other than the cooler lines on the side of the trans.

BUT with all that said, you have every right to be pissed about the cross threaded bolts and chewed up cover....

i took it back to them and showed them what i had found. they will be pulling it in today or tomorrow to see if they caused the issue. The fluid running from the front of the transmission to the transfer case and dripping is light blue and clear. im wondering if when trying to pair the tranny and engine back up they stressed out or damaged the tranny input shaft seal.

I may not be correct about this, but i work on aircraft and deal with replacing shaft seals all the time and know how delicate they are, not lining up the shaft, stressing the shaft, or pressing on the seal in the wrong way will ruin them. if the transmission input shaft seal is the same type i can see how they can mess it up without knowing.

All i know is that it didnt leak the day i took it in, and the week after i got it back i have spots in the driveway and its running back from the front of the tranny and dripping off the transfer case.

I can guarantee they forgot to take off all of the inspection bolts before they tried to separated the tranny from the motor. And probably pried it to the death before they realized it was still connected with just the plate. Lets just say I know a guy who did just that, wont say his name but it starts with an "M", and rhymes with "he".
