1hdt/a442f 80 series. It's the full hydraulic trams. I posted a thread up on mud too. But here is what's going on. When accelerating, the Trans studders significantly when it shifts between gears. It also starts acting like the torque converter is losing its grip after a few seconds. However I can put the truck into park and turn it off, the turn back on and accelerate slowly with no problems. After it gets up to 55-60 mph it will maintain speed for a couple minutes then "loses grip" and revs up again. Seems like decelerating causes it to "lose grip" too. When it "loses grip" all gears are affected and unable to accelerate in 1,2,3 or 4, motor just revs up. I think that's it but I'm happy to try any suggestions or investigate further questions. ANY help appreciated.

I'm pretty sure that the A442F has an electric solenoid for torque converter lock-up. The FJ62's A440F was all hydraulic but not the A442F, if memory serves me well. You might want to check out the 3FE Yahoo list as there are quite a few 3FE 80 series guys there that know their stuff.

So I started going through the A442f maintenance manual and noticed the the 3F torque converter stall speed is 1850 rpm and the 1H stall speed is 1900. Anyone see any adverse affects to using the 3F one if it fits?? Don't think the 1850 rpm would hurt as wholesale auto TC stall speed is something like 1700. I have a spre 3F A442trans and TC is why I'm asking.

Did you check the fluid level? Sometimes low fluid will cause the pump to cavitate and then you lose hydraulic pressure and the trans goes into neutral. Letting it sit for a bit allows time for the fluid to drain back, refill the pan and then you start the whole process over again when you drive for a bit.
