Tifosi, I just replaced the shift shaft seal on my 88, not a bad job and gave me a chance to replace the silentbloc bushings too. It is ready to refill with oil but I have a question: Clutch started to slip at the end of the season (my fault as I was dealing with intermittend 6 cylinder cutout and just the light feel of a TR clutch). I am going to replace the clutch while it is still winter (and I have the parts). My question is WHEN should I refill the gearbox? I haven't looked too deeply into what has to come off to do the clutch but doesn't look like a bad job at all. Do you lose gearbox oil when you take that cover off? I see there are some O-rings which I bought. Experienced stories appreciated. I'm just happy to know my shifter is adjusted perfectly now. Having it all apart makes the adjustment foolproof! Thanks, Cassidy
The 2 holes to the bell housing are above the oil level. You will only lose a little from inside the drop gear case. It is actually easier to fill with the bell housing off.
I pulled the front drain plug to do the job so I'd guess it's 90% empty. I'll do the other just to start with fresh fluid throughout. What I'm thinking is Mobil 1 75w90 or similar and two bottles of GM's Limited Slip Additive. Does that sound reasonable or is there a better alternative? Sent from my iPad using FerrariChat
Good to know. Thank you. Excellent info. I've had the brakes, cooling system, shifter, dash, seats and soon to be clutch out this winter. It's been a busy season of work but she will be right as rain come the spring. Deferred maintenance and some ravages of time, all corrected with time and effort. Sent from my iPad using FerrariChat
No positraction additive. It is contrary to the needs of the syncros. About 99% of the GL5 has it anyway and you sure do not want more.
