Shift fork guide on 901 transmission - 1970 911T
Hello to All
During the process of replacing a shift fork guide cover plate seal, I was in error removing the cover plate before making sure the transmission was in neutral. I am able to see the ‘dongle’ but I am unable to reposition it to allow the guide plate placement for final bolt-up. On a couple of occasions I was able to get the cover ‘home’ but the shifter rod had very limited movement; so much so, I assumed the ‘dongle’ or gear sets were improperly positioned thus compromising any proper gear selection. I attempted to complete this task numerous times with no assuring or positive results. I am at a bit of a loss as to what steps to next take. Haynes, while still a help, doesn't solve my issue. Here's a couple of 'pics' of the part in question:   Any advice or help will most certainly be appreciated. Thanks & Cheers JB Does anyone have any further information on the 'dam seal' as per Grady Clay's recommendation for this model of transmission? The clearance between the I.D. of the release bearing guide tube & the input shaft of the transmission is only about 3mm - pretty tight!!

Through the hole, pop the one shift rod back into neutral with a screwdriver so all the notches line up. Tip the trans sideways so you can see and position the dongle in the line of notches. Hook the guide unit under the dongle and that should be that.

Hello John
I apologize for not getting back & thanking you for your input before now. I seem to have hit a stumbling point here as I am unable to get the notches to line up per your suggestion. This may in part, be likely due to my lack of experience &/or timidity to apply enough force to get said notches to align. This transmission sat for 25+ yrs. so there may be another issue at play here. Having said that, the input shaft turns freely & spins the output half-shaft flanges as one would expect. I’ll be having a “Porsche savvy” buddy dropping over in a couple of weeks to have a look & hopefully he’ll be able help me set things right. Thanks again John & should we ever have occasion to meet – I’ll shout you the beers. Cheers JB
