Strange issue with my 904

You didn't say full manual shift kit. In which case;do you realize that the ROADSPEED has to be such that the tranny is actually in the gear that you have selected.
If the rear wheels are doing zero mph, then no matter what forward gear you select, the tranny will be in low gear. It will stay in low until the governor commands a 1-2 shift. Then it will stay in 2nd until the governor pressure is high enough to command a 2-3 shift.

>But regardless, the verdict is in; You have a fault in the reverse circuit; It should be in the range of 260 to 275, not 55. There has to be a major leak in that circuit.And I can't see it being anything but the VB,the servo, or the seal rings in the hi-drum; you didn't put the Teflon ones with the non-interlocking ends, in there I hope. They are so hard to install correctly.
>The 60/100 you are seeing is about correct. Since 100 is greater than the 55 in reverse,we know the pump is not the problem. Since the servo pressure is also correct at 60/100 we know at least that the servo is in there,lol.
So, I'm sticking to post#3
