Following on from the aod kickdown/tv cable thread, I have a quick question that I'm sure some of you guys can help with. My mate has just installed an Art Carr built aod in his 32 roadster, its mated to a 400 horse 351c , he has installed 2 oil coolers and a deep pan ali finned sump. He has a transmission temperature sender in the car and whilst driving and fully warmed up the transmission runs at between 180 and 210 on the gauge. We think it should be more like 150 tops. Question is do you guys put the temperature sender in the outlet from the gearbox (so it reads the hottest temperature) or in the inlet (so it reads the temperature of the oil after it has been through the coolers) ? If its in the inlet then we are ok as we have it linked up to the outlet so it reads the hottest temperature, if its the other way round then we have trouble I guess. Thanks Paul.
I'd route it on the hot side, that is the true operating temperature of the box itself in my mind. Then again, reading the cooled temperature gives you an idea of what you are sending into the box, so it probably has more to do with how you interpret the reading than anything else. I'd leave it like you have it, in my worthless opinion
Over the years most tranny companies I have dealt with (TCI, the real Art Carr, B&M etc) always recommended that the sender be in the tranny pan and that around 200 degrees was "Normal". 250 for short periods, up hill towing for instance is not uncommon. Have actually heard of tranny's going as high as 350 under severe conditions.
