Hey everyone Im new here. I was just driving fine yesterday for 60 miles. I got home, parked and came back out a few minutes later. Get in and crankit up. Runs good, but when i put into first and start to release the clutch, i get a grinding sound from within the trans. Does it if I try to launch in 2nd or 3rd so im guessing its not the synchros. Mechanic cant get it to grind so hes just replacing a U joint for now. Any suggestions????
