zcarnut Posted October 10, 2007 Share Posted October 10, 2007 There are no sychros on the reverse gear. More than likely the clutch is not being completely disengaged. Check the operation of the clutch master and slave cylinder before dropping the tranny. Early Z’s (1970-72) have an adjustable threaded slave cylinder pushrod. Later Z’s used an auto adjusting slave cylinder. Quote Link to comment Share on other sites More sharing options...

Capt, Reverse does NOT have synchros. How to keep reverse from grinding. When shifting into reverse, be sure the car is stopped. Put he clutch ALL the way in. Then put the shifter in another gear, any gear, 1st, 2nd, 3rd, 4th, (I think most people just use 1st, which I will use in this example). With the clutch pedal pushed all the way in, the car at a complete stop, put the transmission in 1st gear, but only for a split second as you only need to stop the input shaft from freewheeling so reverse wont grind when you select it. Now put the transmission in reverse, and it should drop right in, no grinding. If it doesn’t drop right in, i.e. feels blocked, the gears aren’t aligned correctly so just put the shifter in neutral, let up the clutch pedal, put the clutch back in and go through the same process. That is to re position the gears so it should drop into reverse. I didn’t mention using 5th gear, though you can use it to stop the input shaft from rotating, but the later ZX trannies have reverse lock out which is bypassed by going into neutral, over towards 1-2 before going back into reverse i.e. it wont let you drop directly from 5th into reverse for obvious reasons.

Armand Posted October 14, 2007 Share Posted October 14, 2007 BRAAP is spot on. I learned that too eventually just by ordinary use. I always make sure im stopped when shifting into reverse, and I always go to 5th then down to reverse with the clutch in. Its the best way to do it with no grinding.

m4xwellmurd3r Posted October 14, 2007 Share Posted October 14, 2007 that's what i do for going into 1st. old vw's FIRST gear wasn't syncro'd so i'd naturally go 2nd 1st. I still do that to help it get into first just a tiny bit. I go 5th reverse to get it in. works pretty well imo. Quote Link to comment Share on other sites More sharing options...
