I have a 91 ford aerostar van. XLT rear wheel drive.4.0 liter. When it gets warm or hot. Usually after a hard shift and always from just driving around town when not driving like a perfect old lady. Its leaking from the top somewhere, yes the fluid levels are good. I dont know if its a vent and if a basic trans. Service would work. The shigting and transmission seem to be running great, unless it runs dry of course. Is it the seal? Upper seal? I know its not the pan. To Im hoping we can just have the seal replaced. Someone stated the torque conv. In the tranny may be going bad and causing overheating, Its a 91 and if not a simple venting issue or just a seal leak, I dont want to dump 2 much $.I just need it to get me to school and work for about 3 more months

When you say check out pass side tranny. From below.U mean take a look? Also you the gov. Or accum servo is the leak and u sound confident. So if u r correct what actions need to be taken and does it involve removing the trans.
Thanks

Both are on right side trans and if leaking can replace "O rings" without trans removal
