So I have had my car about 6 months now. It has 105k on the clock. No record of when the last time the transmission oil was changed. First and second gear syncros are toast, but if I am real careful I can get it to slip in without grinding. Got to put it in first just before you come to a stop. I just changed the oil (Brad Penn) and thought it would be a good time to try some SWEPCO 201 in the transmission. The oil that drained out looked pretty good. Still had an amber color to it but a little on the low side. So now with the SWEPCO 3rd has a real notchy feel to it. second will zip on the teeth as I come down from third with my usual methods. First is even more finicky than before. Outside Temp is 35-45 degree range right now. Will this get better over time? Seems like I went backwards.

...in the late '80s and early '90s, Porsche owners with the "flat face" syncros
were having problems with some new transmission oils emerging, at that time; like Royal Purple, for example, tested their oils on Porsche transmissions and found that the boundary layer of their oil was too robust and caused difficulties when engaging gears. The newer tapered BW types did not have a boundary layer problem. If one were to talk to Royal Purple engineering, they would have suggested the use of their RP ATF in the manual transmissions...some did, some didn't. I for one, did not, even with their documented failure mode tests reports. Use manufacturer's suggested lubricant, or its' equivalent specification and you won't need to worry. |
