Ford Repair: E-150 Auto Transmission, 1990,5.0L,302, shift linkage, cruise speed

Question
When you first start it up and take off it shifts fine,but as soon as the engine warms up it has very slow acceleration from stop or cruise speed.I changed fluid and filter along with shift linkage check,tv cable etc. Any ideas?

Answer
I can give you a idea, but it could be a number of things.
1. bad servo bands.
2. bad torque converter
3. low transmission pressure.
I would reccommend having a transmission tech take a look at it. Transmissions are very expensive to replace/repair.. Thanks..
