Anyone ever "fix" a scratchy synchro with fluids?
I have a 6-speed running MTG but it's a huge POS crunch-box. 3rd gear does not like to downshift. Can I add some GM friction mod or AMSoil slip lock and get any improvement?

Never, ever buy a transmission from an auto-x'er, even if he says he only drove it a couple times.

this stuff? AMSOIL - Synthetic Manual Transmission and Transaxle Gear Lube 75W-90 (MTG)
Seems like it would work well, although I'm using this ford motorcraft fluid and noticed a huge difference from whatever the fck was in there previously.
Motorcraft MTX-75 IB5 transmission fluid XT-M5-QS
Although since that Amsoil stuff is GL4 fluid it should be good from what i've read. I LOVE amsoil and it's all i run in my Buell.

This thread is perfect timing. my new to me, sat on a garage floor for a year or two 80,000 km 6 speed shifting was/is horrendous as well.
I might try the motorcraft if we can get it here BUT have noticed in the past week as i use the car more, the gearbox is improving. Perhaps sitting around wasn't the greatest and using it is wearing any rust or whatever off.....
I race national MX here in NZ, the Motul "Pro" gearbox oil is shithouse. Jumps out of gear, won't go in to gear etc....(life threatening on a MX track!)"Downgrade" to the bog standard Motul transmission oil (1/2 price) and shifts are perfect.
I came to the conclusion the "Pro" **** was too slippery and the synchros etc were not coping....told my friends who were haivng the same problem and they all ended up with the same conclusion.
Who knew, oil can be too slippery....!
