Gasket that keeps tranny fluid from sloshing back into the shift lever housing...
Yo,
I've had the problem that tranny fluid migrates back to the shift lever housing then spurting out the hole, ruining the boots.
I was told there is a gasket that you can replace when the tranny is out...well...the tranny is out.
We've looked at the FSM, but I'm not finding it.
1989 NA tranny.
Any suggestions?

Well, you do put gear oil in the shift tower to lubricate the linkages in there, but it's NOT plumbed in to the rest of the gearbox - it doesn't get any lubrication from the gear oil in the tranny.
Anyhow, there's a side plate by where the shifter is - remove that and clean all the crap out of there. Put a thin coat of grey RTV on the plate and reinstall. Do the same for the innermost shift boot where it meets the tranny. Oh, and put a little bit of gear oil or grease in there to keep things well lubricated.
One other common leak is the rear transmission main seal - where the driveshaft goes in. A new one is like $7 or so, and has been re-engineered (at least over the one that was on the tranny in my '86). That will fling gear oil all over the back of the tranny and the shift housing, making a big smelly mess.

There is a small passage in between the gear box sections that allow the transmission fluid to migrate back there.
The way you're supposed to keep the fluid from contacing the rubber boot parts is to keep your inner most boost (with the metal flange you bolt down) in good shape.  If this inner most boot is damaged, it lets the trans fluid hit everything else.

shift tower inner boot
Maybe you can help with my problem. I have a chronic oil leak throuhg the inner boot. I have had the shift lever and inner boot out numerous times, installed an RTV seal between the tranny and the metal plate on the inner boot, used brand new inner boots and I still have oil leaking by a perfectly new, perfectly installed and gasketed inner boot. The only other thing i could think of is that perhaps the oil level in the shift tower is too high? What would be the proper oil level? Any one have any thouhts? BTW, the car is a 90 GTU.

He actually does.
I think he posted something in The Lounge recently?

Shift tower oil leak
Don't fill the extension housing.

Isn't that kind of like burning down the house to get rid of the termites? I would suspect you would need a minimum amount of oil just to lubricate the shift lever ball and socket and the bushings.

Racing beat recommends 90 wt gear oil filled only to the top of the cup that the shifter ball sits in. I won't do mine until I replace the shifter boot that bolts in. Meanwhile I put Moly grease on the pivot ball, bushings, and the bottom shift ball. It shifts real nice now.
