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."

 

i had a similar problem with my mazda b2300 and i caled mazda and they use a special type of transmission fluid and it was causing it to slip.took it in and they changed the fluid and wow now problems.i dont remember what type it was so just call the service tech at your local and the will tell you if you use the right stuff.other car dealers and parts stores were wrong.

 

Remember though that B2300 is a ford Ranger and B2200 is Japanese-made, completely different.

 

Thats 100% correct. At my shop we recommend fluid and filter changes every 40K. If you have went 65 or 70, its overdue but we will still do it. Once people hit 80K though we refuse to do services because more than not you will take a functioning yet overdue for maintenace transmission and render it useless. The description they gave in that post is the exact reason. At a point you are sometimes better to just keep topping it off and let it go.

 

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.
