94 ford ranger v6 4.0l 4x4

[cookie]

my truck shifts gears at the normal 1500 rpms but when I go to punch it the rpms soar but takes long to get up to speed ive asked multiple mechanics and nonone knows I serviced the tranny with new oil and filter and yet still no change really need help ! new exhaust and still same issue.

You would have the last year of the A4LD transmission in your '94

I am surprised a transmission mechanic wouldn't know you need a rebuild, you do, either the bands or torque convert is slipping.
So nothing fluid and a filter would change

I'm guessing multiple mechanics = the guys at Jiffy Lube?

First thought is Torque Converter. Next thought is bands. After that, all my thoughts center on "This is why I don't trust Automatic transmissions"
