Rebuilding my first 930 gearbox, any advice?
I have done a handful of 915's, and a 901 and they all turned out great, so I am not scared, but this is my first 930 box, so if you have any helpful advice or any special areas that I should look at for excessive wear I would appreciate it.
Am I correct in assuming that a 930 box is a little bit more simple than a 915? . Any intermediate shaft bearing issues I need to look at? Fwiw it is worth, this box actually shifts pretty well, and makes no strange noises, and the fluid came out clean without any metal bits, but is starting to grind a little going into third when shifting quickly under power.

It's pretty straight forward. Sounds like your synchro/dog teeth are worn out. Very typical of third gear.
Here's a link I referenced when I rebuilt mine. I didn't get into the diff, as it had been checked out and rebuilt a few thousand miles earlier. Track time is hard on it. 930 transmission overhaul |

If it shifts fine, then it may need some fine adjusting of the shifter, maybe even some bushings replaced. These often overlooked and easy areas can be the culprits with the gates not aligning. Third gear seems to be a problem with these transmissions, though. Even the rear transmission mounts can cause bad shifting. I once had grinding from first to second and went Wevo and from then on, no more problems. There was a guy on here that tried to rebuild his 930 box and ended up wasting it after a few miles, burned up the cage bearings pretty bad by the pictures posted. Ton of money wasted. He ended up buying a rebuilt transmission. It's a pretty interesting post.
I toasted my 930 tranny..... |
