I have a 2004 Honda Odyssey, and the transmission started to go bad. When it shifted, it was very jittery, and I decided to change the transmittion fluid with Honda's fluid. I have never changed transmission fluid before in this car (it is at 136,000 miles). I didn't really empty it out, beause the dipstick had nothing on it. I added more, and it ran like a dream, for about a day. Then, the D4 and tcs light would flash, and then the car would stall. The car would have lots of troubble to shift into 3rd, too. The computers read P1750 and P1751
Does a trash transmissions on yours is shot Honda did replace a bunch of my customers ones but that was years ago contact them tell them Scotty says you should fix theirs for you too and Hope
Well, … check for fluid level and for leaks first. If it run well at first and now is not, loss of fluid would do this. If fluid level OK, no leaks, check transmission electrical harness. Connectors, wiring, … all that. It’s possible you disturbed something, … and now solenoids are not activating hydraulic valves and clutches do not receive required pressure in time and hold.
But, some questions: Original fluid: what condition it was it in? Colour? Smell? Gritty? Drain plug: lots and lots of filings on the magnetic end? All that would mean fluid was bad.
Bad fluid inside, you drain some, refill with new fluid, … new fluid acts as a solvent of the old fluid. This is primarily a result when original Honda fluid was ATF-Z1 and new added fluid used is ATF-DW-1. Bits and pieces of dirt and carbonized fluid loosen up, … flow and jam or restrict hydraulic shuttle valves, car drives bad, … codes are thrown!
Let’s hope it’s just a loose harness!
F.S.
