My B is fitted with a 4-synchro O.D. tranny, which was rebuilt last =
year. It seems that the gears in the tranny have a ceramic like coating =
on the taper that the synchro ring rides on. The bond between the =
coating and the 2nd gear failed, and the coating fell of, rendering the =
synchro useless. This occured very suddenly, one gearchange was fine, =
the next was accomapnied by a crunch of gears, all of which resulted in =
the re-build, after which everything seemed fine for several months.
This spring, when I returned the car to the road after winter storage, I =
noted that the 3rd gear synchro seems to be acting up. It was fine when =
the car was put into storage. All new synchros were fitted during the =
rebuild. =20
I have noted that the tranny oil level is down a bit, below the low =
level mark - I don't know how much down this mark signifies. The =
mechanic who did the work - only does Brit Cars by the way, uses 90 =
weight gear oil in all trannies, and this is what he filled my box with. =
Also, when I drove the car, the temperature was quite a bit lower than =
in the summer when the car gets most of its use.
What is the list wisdom on 90 weight in the trans? Could this account =
for my problem? I know that 20W-50 is the normally reccomended fluid. =
How about the low oil level? Anyone have a feel for how low the =
transmission is if the oil drops below the low mark on the dipstick?
Best Regards,
Chris Delling
