So I've been having a problem with third gear. When shifting through gears some times 3rd grinds when going from 2nd to 3rd. But when down shifting it grinds every time, 4th to 3rd. Anyone had this problem or know what it could be?
As always thanks for any help! -T |

I had the same issue.
Most likely the syncro's are dying, seems to be common for the 3rd gear. You can try changing out your transaxle oil to see if that helps. -------------------- |

Always been pretty good with my hands and figuring stuff out. But with this I wouldn't even know where to begin. Thanks |

Thanks You need a rather large socket to remove the drain plug and fill plug, it may have been a 22mm on mine. First step is to remove the drain plug on the lower driverside of the transaxle, directly under the driverside cv axle shaft. Once you have drained all the fluid, you need to reinstall the drain plug, I dont know the torque spec off the top of my head but its fairly tight. Remove the upper plug, it is on the front of the transmission, somewhat on the underside facing downwards at a slight angle. It is the same size as the drain plug. The ttransaxle will take exactly 2.7 quarts of 75-90W (I think 75-90) gear oil, but everyone suggests Pennzoil Synchromesh Fluid in this weight. The Pennzoil is known to fix third gear grinding in our transmissions. If the car is on a perfectly flat surface, 2.7 quarts will bring the fluid EXACTLY level with the drain plug hole, so that if you were to put 2.8 quarts for example, .1 quart would come spilling out. This is all for the GT, I dont know about the ST 5spd |
