hey guys





dunno if this has been asked before. Anyways, i picked up a 93 RX-7 bout a month ago and when i shift into 5th gear it always grinds. ONLY 5th gear. is this a common problem? thanks

 

Yup, that also happens to me?

 

Common problem.. with age... most people mis-shift from 2nd to 3rd.. and accidently hit 5th.



You can fix this by rebuilding the transmission, try redline fluid, might make it go away, or you can learn to align the synchros manually.



You can also later put a short shifter, or a torque brace to fix it. You should also have your motor mounts checked out.. sometimes those will be bad and create problems.

 

shift slower...that might help

 

very common on 3rd gen rx7s you can get it replaced locally or you can do it your self. i fixed mine myself for a about $100 in parts and extra tools i needed.

 

Heres the online instructions i used a year ago. http://mahjik.homestead.com/files/hosting/...ro/synchro.html



thanks majik for hosting them. if you ever come by our way

 

just take it slow when you shift into 5th and try to match your revs



it will prolong the time needed for you to get it fixed



and an engine torque brace would be good too

 

thanks for the replies





another question...a torque brace will fix this problem? or itll help prevent this problem again in the future? confused.....



i guess i shoulda put it in 5th gear during test drive before picking up the RX7..

 

yup. the engine torque brace is supposed to help. i have that same problem so i ordered one of these. http://cgi.ebay.com/ebaymotors/ws/eBayISAP...item=2466520138 it's the exact same as the FEED one but it's not $400...

 

Call Ray at Malloy Mazda for prices...For both the spindle (which you need to change as well) and the improved OEM 5th gear synchro, it was just under $60!!! Not a bad price at all. His number is: 888-533-3400. He owns an FD and is well known throughout the forums. GL!!!
