    Well I have a VDO guage w/ a probe in the tranny oil pan. The "expert" I bought this tranny from says it should never climb above 165. I find that really hard to believe. I have the biggest cooler available. I have replaced everything in the cooling system, the engine never gets above 190 but the tranny can get significantly higher than 165 during stop and go or sustained 2nd gear climbs, this is UNLOADED. I have the option to lockup my tc in any gear but I cant say if this makes any temp difference. What temps are you guys seeing? Thanks.

    I don't remember right off... but I think it was somewhere around the 200-210 range.

    How is this installed? It sounds like a good thing to have and would be interested in installing one?

    You don't want it over 200 for too long. It can hit 250, for a short period of time, but you don't want it that hot for too long. I would back off it if it get's over 200 for too long. I think the normal driving temp for R4's are like 180 or so give or take.

    At 260, really bad things start happening. I'd say if it stays under 220 all the time, I'd be perfectly happy.
