90 Honda Accord Transmission Woes!

[HondaGal777]

I recently purchased a 1990 Accord, the previous owners clamed that it had a bad automatic transmission. While driving the car home it started slipping while trying to change from 1st to 2nd, and from 2nd to 3rd. The car would barely move. Knowing how Honda's don't run well without Honda fluids, I cchanged the fluid to Genuine Honda ATF fluid. I drove the cars several short trips with no problem. Then I drove the car about 220 miles each way on a road trip...again the car was great. When I got back home my husband drove the car about 8 miles and it started slipping again. I changed the fluid once more to see if there would be any change to it, there was little effect. Since then I have driven it a few more times....some times it slips, sometimes it does not. The car routinely goes at least if not more than 7 to 10 miles before it slips. The computer does not flash any codes at all.....Any one got any ideas? Would the shift solenoid cause this intermitant problem or could the shift position console switch be to blame? Or will I have to actually replace the transmission?

Thanks to anyone that can help with this!

I think you have a bad tranmission. Slipping is usually bad bands. How many miles on the car?
