overheated transmission

Cel?

have you check your transmission fluid level, usually it is low when it produce a lot of heat.

Something is toasted whether by heat, mileage or driving technique. I have heard that heat is what wears many slush boxes out. Perhaps a fluid change and a transmission cooler might bring it back for a while. Remove that grill block to see if that helps. If you are using your AC turn it off. Run the heater. What does your Scan gauge show? Any codes?

You have been making your transmission do things it was not designed for. ei: shifting into N and back to Drive. I am sure that the manufacturer did not anticipate owners doing that. Quit shifting your auto into N and back to D while rolling.

Looks like even mcrews expensive car must have a cooling issue with a grill block.

Everything is fixable. Keep telling yourself that you want to learn what the inside of your transmission looks like.

The transmission seems to work fine untill it warms up, then the speedometer and odometer both die.

Fluid level is fine and not burnt smelling. I tried replacing the filter to the transmission, but this generation of Civic does not have a serviceable filter for the transmission.

Should I start a dedicated thread ? Or if you feel up to it perhaps you can PM me OldMech.
You were helpful once before in the past when I needed advice on the car.

It may be different for honda, but most transmissions have an input and an output speed sensor. when you say the gauges go dead the first thing i think of is electrical.

I removed my lower grill block and already it is shifting better. I might add some seafoam tansmission cleaner to see if that helps more, but I have an apointment for a flush, filter and fill.

Have a look at the car's internals to see where the transmission fluid radiator is, and leave (at least) that end of the grille block open.

The tranny cooler is one of the things NOT to block when closing off the lower grille openings

If you are going to just have the fluid flushed out do it yourself since the trans filter is not being changed. Get a transfer pump and pump the fluid out replace the fluid drive it for a day and do it again. The torque converter will have old fluid in it even with a shop flushing it unless they have the trans running.

I just thought being a Ford you might have one of there sealed trans and I'm not sure how to access the fluid that way.

the fluid and filter were changed and there is no longer any hesitation. they said the fluid was a bit dark but didnt smell burnt. it was a former lease vehicle and i dont know when ithad the fluid changed last so i guess it cant hurt much but my wallet. after i got the fluid changed i filled the gas tank and added a can of Seafoam. I took a spirited drive through the gaspereau valley road to mix the seafoam into the fuel and to give it an italian tuneup. it felt like it got more responsive after about 5 kms. It could just be a placebo effect!

Valid concern. Not all vehicles route the tranny cooler through the radiator coolant which means if the coolant over heats so does the tranny fluid. Some just use a metal tube or a small core off to the side or in front of or below the drivers side head lamp behind the bumper.

This!
I was having radiator probelrms (ranch road dirt and dust had clogged it up!) and installed the coolers and the gauge to keep an I on it.
