boost69 Donating Members 737 Member For: 19y 11m 19d Posted 11/01/13 07:19 AM Share Posted 11/01/13 07:19 AM Guys,I have put an air to oil tranny cooler, on by BF, (ZF) but have noticed the thermo fans are coming on far more often since the install.Does anyone know what the ideal tranny oil temperature range is?Would my tranny oil getting hot trigger the thermos to go off..?Is there a temp sensor for the tranny oil?If so, can a run of the mill obd11 scan tool read the tranny oil temp?I'm sort of worried about getting air flow to the cooler when stuck in traffic on hot days.Any input is appreciated.Cheers Link to comment https://www.fordxr6turbo.com/forum/topic/83530-transmission-oil-temperature-range/ Share on other sites More sharing options...

old_mate Member 767 Member For: 19y 2m 25d Gender: Male Location: Brisbane Posted 11/01/13 11:21 PM Share Posted 11/01/13 11:21 PM Have a look at the last few pages of the link above, if anything your trans temps will be way cooler than before. Warmest I have seen is 85degrees after a thrashing at the lights, coolant temp was 99. And it dropped back to the 70s once at 70kph for a few minutes. My cooler is also behind the foglight.

Getting my zf serviced on Friday though. Been a bit funny at cold lately not wanting to change gears till I'm doing 3000rpm at slow acceleration so hoping the new fluid will fix that.
