AT oil cooler & diff question

[mtechnology]

when i drive for a good while I can feel the heat rising up from where i shift my automatic transmission. i have a 95 316i compact and this has been going on for over a year. could my AT oil cooler be faulty? maybe the filter? or a heat shield missing...?

also i have a loud hissing noise coming from the differential area when im driving. i have been told its my front diff bearing but i was thinking of checking the drive axle bearing first. if it is the diff is it worth changing the diff bearing or should i look at getting a new diff.

thx 4 any help and congrats on an excellent bmw forum

welcome to bimmerwerkz..

for the whole heat at the gearbox issue, i notice this as well in my manual tranny, but nothing too substancial , just sometimes i notice it sometimes i dont, ive never actually inquired about as the performance has never been affected..


as for teh diff , the only real way to know is by having the car in the air, and running it while in the air to pin-point the exact spot, do you notice any leakage from teh seals?

no leaks from the diff plus i changed the oil
