The clutch went out on my 97 tj. I took it to a local shop and after replacing all the clutch components they still cant fix it. They claim it is a mystery year transmission because it is a conversion and has lost its serial #. They also say they cant find the correct slave cylinder for it because of the same reasons. I meet with them tomorrow. Does this sound reasonable? They are giving up and want me to take it back. Originally they thought it was the clutch master and I authorized replacement. They then replaced the slave without my ok. Then they said it was a bent fork and I agreed to its replacement. They have since replaced the clutch plate pressure plate and throw out bearing without my authorization. What do I owe them?
