Well, I had my jeep worked on yesterday. The problem was a solenoid, governor pressure failed. They used:

Gasket OI 21004003
Transduce 21030410
Solenoid 8059043
Oil Autom 1081018
Solvent


Also, the DRB III test found an oxygen sensor was faulty. So they replaced the
Sensor OX 8037155

All of this cost my $50 - the warranty deductable - and the jeep runs fine.
