ZF Tranny Problem

[birdshill123]

I am wondering if there are any ZF experts on the Forum. Twice in the
last 12 months I have had A small problem. First time I was stoppped
in a construction zone waiting for a backhoe. I started to accelerate
and then had to back pedal as there was a huge hole. I dont remember if
I was in 1 or 2 but when I reapplied the throttle it seemed to be
either slipping or was in neutral. I put it in neutral and then in D
and away we went. Everything was fine. Yesterday I stopped at a toll
booth in Mexico. I hit the throttle and then had to back of as there
was a pedestrian very close. Again when I reapplied th throttle it
either was slipping or was in neutral. Again I put it in neutral and
then D and it took off. I am wondering if this is some quirk of these
trannies or maybe a hydraulic pressure problem: A valve that sticks??
Any suggestions?? I will be calling ZF tomorrow.
