Hello, My car transmission (auto) seems to disengage for too long sometimes when changing gears. The revs will raise up but then after a second or two drop back into gear. It seems to happen when i a

change filter could help for a minute but clutches are fried in drive

hi Hamish, what you describe is called a 'flaring shift' when revs
don't correlate to vehicle speed due to a slipping auto.
have you rechecked the auto oil level when the engine is running,
sometimes they take a long time to fill because the onboard oil
pump in the auto in very small.

4th gear disengagement:

The 4th gear is engaged automatically after the transmission has shifted through 1st, 2nd and 3rd gears

at certain speeds and loads. By pressing in the button at the rear of the selector level, the 4th gear can be

disengaged, thus providing a three-speed transmission. As a reminder the

? light on the dashboard

glows. By pressing in the button again, the transmission reverts to four-speed operation and the

?
light shuts off.
This is straight out of the owner's handbook. What this indicates is that there may be a problem with the shift solenoid. On the highway, does is seem to rev high? Can you press the button on the shifter and have the light go out? let me know.

The fast idle valve is inside the throttle body. Sometimes it backs out and needs turned back in (it's threaded). This will cause the loping idle.

Get transmission filter changed with new fluid. Honda does not recommend transmission flushing.

Have he transmission drained and the screens cleaned

do not flush the trans, that will make it worse.
My friend you have no second gear, you need trans rebuilt.
If you flush it now you can cause more damage.

Yes you have a Transmission problem that is only going to get worse.
There is nothing to do now that will solve this problem. You can pull the dipstick and look/smell the fluid to verify this but unfortunately the only thing to do now is have the transmission rebuilt/replaced.
Sorry to be the bearer of bad news.

hi do the simple bits first check the fliud level in the box see if its a clear redish colour if any other colour you have a box problem second when was the last time you chaged the boxes oil and filter a blocked filter will cause your problem then the box itself first clutch could be slipping put the box in first gear chock your wheels up put the handbrake on put your foot on the brake pedal start the engine and rev with your other foot and see when the car stalls it should be around 2500 and 3000 revs if its higher than this the clutch is slipping on that gear after this you will need to take it for pressure testing yates210456

You have an overdrive relay issue. The tansmission is really a four-speed box, but the OD selector either locks our fourth gear or allows the car to shift normally into fourth. I use the OD on my volvo all the time, because the revs drop in half when the OD is activated, The relay is located behind the glove box, toward the center console. $10 buck on Ebay and your transmission should shift correctly again. I would try that BEFORE more expensive fixes, like OD solenoid $200 or transmission control module. Just for kicks a picked up a spare ECU on Ebay for $10 because these get costly if and when they go. Easy fix, though, a couple of plugs.
