Sounds like you have a vacuum leak somewhere.
Check all hoses for cracks and hard and/or brittleness.
Vacuum MUST be correct for trans to operate properly.
PSIG lives up in nowhereland with you two too?
I always thought it was a special gear they put in trans. Just like muffler bearing grease and Blinker Fluid.How many think "passing gear" is something different than second gear?
