I have a 95 f150 4x4 w/350k+ miles on the original transmission, was wondering what fluid is best?
A lot of posts are old as well as spec sheets but looks like mercon 5?
Last fill was Mobil 1, but doesn't say mercon
I've got the factory trans cooler, bypassed the radiator and a derale deep sump pan w/cooling tubes. Transgo shift kit since 60k, I've had a temp gauge installed when it was still under factory warranty, and highway temps in the Texas summer are 120-140f, traffic around 150f, heavy 4x4 off-road 160-179f.
Is this normal temps?
And I've always done 5year/60k fluid/filter changes, cleaned the magnet, drained the torque converter, disconnected and drained/flushed the trans cooler.
Still shifts and runs as good as when I bought it back in 97. I want to see how many miles I can get out of it. Mileage is 359k+ because the oem computer was replaced@180k, and my current one shows 220k but I'm running larger tires so it's really a guestimate....thanks
