Many modern manual transmissions use atf as the lubricant.FruDaddy said:Manual transmissions and car engines don't have the need for the friction agents, so I don't feel that their lubricants are appropriate for a motorcycle transmission.
Maybe true, and many automatics will eventually fail it ATF is used._JOE_ said:Many modern manual transmissions use atf as the lubricant.
showtime586 said:My local shop sells Bell-Ray transmission oil and gear oil. One was labelled 75w, the other was 80-90w. Both had the hydraulic fluid look to them, and I was wondering if the different labelling wasn't just a marketing strategy (possible for thumpers) or if there is actually a difference (other than viscosity)? I asked the parts guy and he didn't know. Anybody know? Thanks

Good. As far as I know the main problem with non-bike-specific lubes is clutch slippage. Other than that they all do basicallt thsame thing. They lube bearings and provide a barrier between gears. I'm sure there are some other minor differences. Most owners manuals recommend like 10-30 or 10-40.showtime586 said:DL,
The 80-90w is definatley called Hypoid gear oil, but it isn't the thick variety. The viscosity is only marginally different than the 75w tranny oil.
The 80-90w gear oil that i used to put in my outboard lower unit was very thick, and had an unpleasant smell.
At any rate, I got the 75 tranny oil.
