Hello all. I have been having a problem with the transmission in my 97 Civic. It used to slip 3rd and 4th so i put a new one in. It still slips but only 3rd. I was thinking it was the trans computer but someone told me that there isnt one. Is this true? If not could someone please tell me where it is located in the car.

Thanks in advance

Dan

 

trans computer?

 

Your vehicle is run only by the PCM (powertrain control module). There is no seperate TCM (transmission control module) that controls your trans.

 

There is no TCM, this isn't a Jeep.

When was the last time you changed your transmission fluid?

 

You said it used to slip in 3rd and 4th so you put in a new one. ? A new what ?
Flush the transmission fluid. There is a TSB for 6th gen civic auto trans. = Linear solenoid. Do a Google search
Flush procedure:
Honda Auto Trans Flush = 1 case of Honda ATF (12 qrts) $50. 1 new drain bolt washer $1.

1) Put the front of the car up on jackstands with the wheels off the ground. Put a large container under drain plug.
2) Remove the transmission drain plug (3/8" drive ratchet works fine). Let transmission drain and wipe sludge off drain plug.
3) Reinstall drain plug and snug (not tighten). Fill transmission with three quarts of ATF.
4) Start engine and shift into drive. Gently accelerate and let transmission upshift through the gears (don't go over 50 MPH).
5) Step on brakes and bring speedo to 0.
6) Shift into reverse and accelerate to 20 MPH.
7) Bring speedo back to 0 with brakes. Shift to park and shut off engine.
8) Repeat steps 2 through 7 TWO MORE TIMES.
9) Drain the transmission once more. Reinstall drain plug and tighten firmly (don't forget to reinstall crush washer).
10) Remove jackstands and put vehicle on level ground.
11) Fill transmission with 2 1/2 quarts of ATF. Start engine. Shift to drive, then reverse, then put back in park and shut off engine.
12) Check transmission fluid level. Top off if needed to bring fluid level to the top of the crosshatch marks on the dipstick.

 

Thanks for all the info. I have read the TSB on that solonoid and have contemplated installing the one from the old transmission to see what it does. My mechanic told me not to put Honda ATF in because it will make it even more slippery???

 

...............I would stick with Honda ATF
PLEASE reply back after you drive with the swapped solenoid.....let us know the results. Alot of people have Auto trans issues !
Thx

 

Will do... It wont be for a lil though as there is a bit of snow lying around still and i dont own a lift lol.
