Transmission grinding help!

[Jaysblacktalon]

Never ending problems first alternator then wheel bearings now my transmission, well anyways transmission is grinding from 1st to 2nd only does anybody know if i just add lucas lubricant for transmission would it help? or should i rebuild the whole thing?

maybe clutch but i think its going out...! when you shift from 1st to 2nd if you let the rpm's go low in between gears will it not grind... if so then i think its your tranny going out,,,

Probably your syncro, my old tranny did that too.

Save up $1,000 and send it to sheptrans.com that will fix your grind.

Try some PREMIUM gear oil like BG Syncroshift (what I use) or Redline. Its worth a try it'll only be a bandaid though if it works.

Start shopping for a transmission...

I've got some gear lash and a worn input shaft because of a botched rebuild (long story). Anyway... after loosing count of how many different gear oils I've tried to quiet it down and smooth it out, Redline MT-90 was the only thing that works and almost makes me forget about it. (I also switched to Redline Heavy Shockproof in the t-case and rear diff, and will never use anything else again).

But Omega is correct...it's just a bandaid. I plan on dropping mine for a rebuild and clutch upgrade in the next few months, but in the meantime the MT-90 is helping significantly.

Either adjust your clutch master cylinder rod at the pedal assembly toward the firewall (clockwise) -- as you may not be fully disengaging your clutch.

OR

Drain your transmission and use Redline MT-90 gear oil. Do not use Lucas thick shit in the transmission. It is nice to use when rebuilding a transmission or engine as an assembly lube, but NOT for normal use in a transmission.

OR

Get the transmission refreshed. It may be able to get away with just a stage #1 rebuild that replaces the 1/2 hub and slider, 1st gear synchro, 2nd gear synchro, 2nd gear, and bearings. You could easily have an intermediate shaft bearing failing causing the shifting issues as well.

Good luck,
