transmission question
I have a '95 Explorer, 6 cylinder with 100,700 miles on it. I have changed
the transmission fluid regularly and have had the system flushed out each time. Is there anything I should be doing other than this? Does the transmission need to be adjusted periodically or something like that? I have noticed lately that in the morning when the car is cold [I live in Wisconsin] that it seems to take about 5 minutes or so for the rpms to go down to "normal" and during this time, the transmission seems to be in a lower gear and then it will go into a higher gear and the rpms go down. Is there something I should do, or is this ok. The car seems to run beautifully, and I've always changed the oil every 3000 miles, and done the service stuff when needed. Thanks. |

Sounds like good servicing practices to me. It also sounds like the
torque converter clutch lockup (that last "shift" you feel) is not ocurring (at over 45 mph) until things warm up a bit and the extra loading comes off the tranny. This is pretty normal in these cold winter temperatures. Things are pretty thick those freezing morning hours there in Wisconson and here in Michigan. If things don't go back to what you think is normal after temperatures warm up, then you might want to look deeper. Right now I wouldn't worry about it. Good Luck - Pray for Spring:-) |

Jacob - Do you change the tranny fluid yourself, and flush it? Is it a
pretty easy job? What do you flush it with? Any tips would be appreciated. I want to start working on mine more myself. Thanks, Allen |

I don't have a clue about cars, and take it into a service place and have
them do it. The cost for the transmission flush is usually about $70, and they tell me that they hook it up to a machine that flushes out the fluid and replaces it. The last time I took it to another place and I'm not sure if they flushed it or just changed it, but they did change the filter, which I don't think they do when they flush the system. I'm really not into working on cars and don't have any tools or anything else. Good luck working on yours, maybe someone here would be able to tell you how to do it. Also, does the transmission need to be adjusted periodically? Any suggestions would be helpful. Thanks. > wrote in message oups.com... > Jacob - Do you change the tranny fluid yourself, and flush it?

Thank you for getting back about this and your excellent explanation. I
still would like to know if there is any need to have the transmission adjusted or something like that. Does a transmission need a tune-up like the engine does?

Generally, any required regular adjustments would be covered in the
maintenance section of the owners' manual. I don't recall seeing anything except fluid change. You are probably thinking of the old days when band adjustments were required.
