Wait what? Air? How do I get air in the system, and more important, how do I get it out? :S
You said you replaced the transmission, right? Any time you do that it is a natural occurrence to get some air in the system upon assembly especially since you said the transmission had been setting for 8 yrs. so every drop of ATF probably drained out of it. If you re-read my post I said the air works it's way out of the system naturally so there's no need to over-think this and worry. It'll be fine after a trip around the block.
Altso I broke part of one of the cooler pipes while unscrewing it from the trans, the guy at my local amcar-store said I could just cut it and place a fuel hose there because the pressure there was kind of low, but is this true or could that be the problem?
