Alright so I'm driving home from work. I shift it into 3rd and I hear it grind into gear, but it dives perfectly normal in 3rd. Now if I downshift into 3rd then there will be no grinding. Also if I shift really slowly into 3rd then no grinding is heard. The grinding is only heard under quick acceleration and medium to quick shifting. Any idea what could be wrong
-------------------- I only want to be faster than the guy next to me.

QUOTE (mkernz22 @ Oct 23, 2012 - 9:43 AM)  Looks like I'm going to have to get some syncromesh for the spring when I do everything to my car lol It doesn't grind going in when I'm going from 2nd to 3rd, it is a little hard, but say I'm in 5th, take it out of gear for a few seconds, then go to put it into 3rd, it'll grind half the time. All the syncronizers do is match the speed the gears are spinning at to the speed the wheels are moving at. If the clutch is engaged then the engine will spin the gears. So if you were to double clutch, or if you were to rpm match and slip the transmission into gear without using the clutch then you would totally negate the need for syncronizers. This is because either way you will have used the engine to bring the internals of the transmission to the same rotational speed as the wheels. For slipping into gear-Because of the design of the teeth on the gears you have to rev the transmission and engine FASTER than the next gear, and then slowly let the rpms drop until it slips into gear. If you were to rev the engine until it hit the correct rpm it wont grab into gear. You must rev it higher first and then drop the rpms to match. As for double clutching the first thing you need to do is depress the clutch and pop the transmission into neutral, next rev the engine to the approximate rpm it needs to be at in the next gear. With the engine at the desired speed and still in neutral, release the clutch. Now depress it again and quickly and shift into the next gear. Because you dumped the clutch in neutral you forced the transmission to spin at the speed the engine is going which is also the speed of the wheels and the next gear if you were accurate. Syncronizers are for plebs... Serious business though, I would never let a tranny grind on me, you never know what disease it may give you.
