ZF Tranny Problem

[Juergen]

Bruce
Best thing to do is consult ZF. It could be as simple as low voltage to the ECM or the transmission shift selector starting to get tired. (Dirt, Dust, Corrosion, etc)
Be sure to check your tranny oil level. It must be at the right level. Check as following:
Cold - Vehicle level, shift selector in Neutral, Engine idle 600rpm, after 2-3 minutes check oil level at the cold zone.
HOT same as above except no 2-3 minute wait and Oil level should be at hot zone.
ZF doesn't have quirks like me with this computer, ZF is telling you something thats in the making. Could take years to finally happen.

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.
