ZF Tranny Problem

[Donald Spithaler]

Hi Bruce
I know I am a long way from an expert on them & I have never had
that problem. I did have ZF install a new E-Prom because I thought it
didn't shift up & down as should. It was an upgrade. The E-P was
$154.00 parts & it did make a difference it the up & down shift. I do
know you have to get a full 12 volts to the E-Prom .Blue Bird put
20-30 amp Bosch relay . That was before I had the new E-Prom.
