Is it an upgraded rebuild? , would be fun to floor it whenever one feels like doing so 🆒I got my 99 trans rebuilt by level10 a few years ago. So far it's been fine. Yeah a few bucks more but sometimes you get what you pay for. After reading all these posts about transmissions on this forum - I would only want a Honda trans specialist to do the work.
Your son drained the fluid and added 5 qts and then ? the transmission started slipping?Why not just try the fluid change? My son “changed” my daughters transmission fluid in her 2000 accord but since he had no clue drained the transmission fluid and added 5 (it only holds 4) qts of oil. He then proceeded to drive it around with no transmission fluid. Eventually transmission started slipping so he decided the fix was he put too much oil in the car so he drained more transmission fluid and drive the car some more. At this point I assumed transmission was toast. It was slipping, not going into gear. 🙄🙄
After sitting for 1.5 months, I was teaching her a lesson about having inexperienced people touching her car, I added max life trans fluid. Ran it through the gears, did a drain and fill, drive the car and it finally drive and shifted but it was rough.
I then removed the return line, drain the fluid 3 qts at a time while adding new fluid, ran a total of 2 gallons through, then added a magnefine after all the fluid was clean. The car shifted better and she was able to drive it without all the jerkiness and slipping. This was Sept 2020.
4 months later I did another 2X drain and fill in Jan 2021. I just did 2 more drain and fills in Aug and also replaced the magnefine. It has been 10k and transmission is shifting fine, the only issue it has is that it jerks on occasion when coming to a complete stop and if you drive like a maniac it slips going from 1-2.
3 gallons of max life and a few hours of my time.
