4-speed gear oil matinence...how often should I......

[66340SEDAN]

Have a 833 trans in my Valiant, it was rebuilt 7 years ago and has about 6K miles on it. My question is when should I change the gear oil in it? I run the car hard and do grind them once in awhile LOL Nothing special for oil, just Valvoline is what I run in it.

Also, how often should I grease or lube up the Z-bar/bell crank bushings and any other moving parts associated with the 4-speed? This is my 1st manual trans car, thanks!! BTW, it all works fine, just curious :glasses7:

Oil is clean and like new, good color and smell, trans shifts nice

well 7 years is still a long time ...and it could have attracted more moisture than you might think in that time.

everytime its hot and cold there could be condensation ....after 7 years i would definately change it

I put Schaeffer oil in the bikes trans. It is a fluid pretty much made for Harley style transmissions. PITA to get in a quart bottle. When into the sales rep in NAPA once he said to let it go 25k milers or so. Not going to happen. Manual gearboxes I have always liked getting the fluid out of them on a regular basis, just to check for chunks of metal and what not. Sure, magnetic drain plugs will catch most if not all of them, but I still like to dump it regularly just to check. But I have more than a few goofy traits so.......
