Sounds like your clutch isn't disengaging fully. Keep the clutch pedal depressed for 10 seconds then try to shift into reverse. If it grinds, your clutch disc isn't disengaging for some reason.

you might check the fluid level and find out what kind of tranny fluid they put in

Since you passed the "reverse test", perhaps the tranny fluid wasn't replaced with the proper weight oil. The transmissions use ATF which is very light weight oil. If someone mistakingly added something like 90 weight gear oil (like was used in the old days) that could be the cause of your grinding problem because the synchros will not allow meshing of the gears as quickly.

You will need to get the car on the lift, remove the drain plug, actually just crack it and let a little run out. If it's pink, then it's ATF and you might have other issues. If it's some other color such as brown or purple and feels thick, then it's gear oil. Have that stuff completely removed and have ATF put in. Then take two aspirins and call me in the morning! :lol:

Can you find out who did the install of the new parts? Is there a warranty still in place? Maybe check with the installer.

You do not drain the trans from the rear end !

What Rob said. It sounds like you drained the differential. Our cars do not have a trans-axle. The differential is separate from the transmission and contains different lubricant.

yes, i found out that they are seperate ( I am still learning) but I dropped off car yesterday at my local transmission shop. they said the fluids are fine, the mounts are fine, everything exterior looks fine? I guess I will take it back to the shop that replaced the transmission and see what they will do, my mechanic here seems to think with everything being new it may just be clutch adjustment or something wrong when they put the new clutch in with the new syncronisers. Has anyone heard of a LUK clutch? is it good? anyone else had these problems?
