2001 Excursion 4x4 4R100 transmission lost all forward gears. I've recently swapped in a 6.0 31 row trans cooler in hopes of reducing the trans temp.
Before the trans cooler install, I've been noticing that after driving in normal trans temp for a while and parking it, after coming out of PARK and shifting into drive, I'd have to rev up the RPM before it engaged in Drive. Or, I would have to shift into 1st, then Drive.
On a 30 mile trip since the trans cooler install, the trans began to slip in O/D, 3rd & 2nd. I limped home (all the while) the temp was averaging 175-180 in 100 degree heat here in Atlanta's traffic.
Trans fluid is not burnt, but haven't dropped the pan yet. After letting it sit for the past several days, I drove it to Costco via the Highway (2 exits away). All shifts seemed firm and normal. Once I arrived at the stop light a the exit, it was as if it was in Neutral. No shifting in Drive nor 2nd Gear, I limped up to Costco and let it set. Once leaving, I could only limp out in 1st. No drive or 2nd gear (REVERSE IS FINE).
After about 3-4 miles in 1st, it gave out and had to get it towed back home.
Background on the truck.
7.3, 4x4, 4 inch exhaust, triple gauges, SCT canned tune performance, 37" BF Goodrich tires, 8" lift. 195K miles on eng, most likely stock original trans.
Can anyone recommend a reputable trans shop in the Atlanta area?
