On my recently purchased WJ (4.0/42re/factory trailer tow) I noticed that the owners manual says check the ATF level in Park, while the dipstick says Neutral. In Park it appears to be 1-1.5 pints overfilled, in Neutral about a pint under. I'm tempted to split the difference and leave it alone, but I'm curious what the FSM says if someone has one. The FSM for my old ZJ says Neutral because the converter and cooler are bypassed in Park(also the reason for slow engagement after sitting for
3-5 days)and that's how I always did it. The owners manual for the WJ mentions the 5 second delay, so it doesn't sound like it should be any different.The AC condenser/trans cooler assembly was taken out and repaired at some point and it takes a really long time to get the fluid hot. There is no in-radiator cooler, so maybe that's to be expected, but I'm wondering if I have a malfunctioning cooler bypass somewhere???
The first time the torque convertor locks up is usually harsh and it crunches shifting into reverse, otherwise it shifts fine.
