My ‘97 has 260k miles on it. Running 5.29” gears in the diff.
I had the transmission oil changed less than 10k miles ago and have a temperature gauge installed with the sensor in the pan. What I struggle with is keeping the temperature manageable off-road especially on dirt roads where speeds is between 15-30mph.
If I run in 4-lo, it tops out at 25mph with RPM at about 3k and I guess there is no OD in 4-lo. Eventually the temperatures start to climb.
4-Hi isn’t a good option either obviously. Shifting down to 2nd or L doesn’t work well either since I can’t lock the torque converter.
Wondering if pretty much everyone ends up installing an aftermarket torque converter lockup unit or my tranny needs a rebuild? I have noticed that once the pan temperature crosses 150F, the tranny starts to behave very odd. A few times when I have come on the freeway after hours of trail time, the tranny seems to get stuck in OD and if I step on the gas hard then it shifts down momentarily but shifts up quick and won’t stay locked to pull the truck. Usually end up with see saw effect, at which point I quietly move to the slow lane and lick my wounds.
Is this normal for the A343F or should I look to get my tranny rebuilt?
