1989 B2200 Tranny slipping after filter & fluid change
I own a 1989 B2200 Automatic 2wd. Last week I changed the tranny filter & fluid. Now when I start the truckand switch gear to take off; the tranny slipsfor about 20 seconds or so. When I make a stop and take off it slips again.

first Thing that came to my mind is do you have enough fluid in the transmission? kind of obvious but... as well when I typed in your generic title without b2200 I got a return with this blurb in it
" learned about this problem several years ago...the hard way. We had two cars in our shop with these "minor" transmission symptoms that I have listed above, and both of them had to be towed out to the transmission shop after servicing. The old fluid was gritty due to metal shavings caused by normal internal wear and tear on the transmission clutches and was acting like liquid sandpaper. This "sandpaper" was producing the friction needed for the transmission to pull itself. When we changed the filter and replaced the old fluid with new fluid, the clutches inside the transmission had nothing to grab on to. Sometimes even the best of us learn lessons the hard (and expensive) way."

Also keep in mind that Automatic transmission fluid is a detergent, as the fluid gets older the detergents will get used and eventually deposits will form inside the transmission, once this happens changing the fluid is a death sentance since the new fluid will break down the deposits which will release in clumps. These clumps will clog the small passageways in the transmission causing it to fail shortly after.
The first automatic transmission I ever rebuilt locked up on the tranny dyno after it ran about 45 seconds. Everything was assembled PERFECTLY, what locked it up was barely a pinch full of paper towel lint which clogged a screen covering a passageway.
Automatic transmissions are very sensative and if you don't perform their maintenance EXACTLY as recommended they WILL fail. Too much fluid can destroy one just as easily as not enough as well.
