Do you have your transmission fluid and filter serviced? I'm closing in on 95,000 miles on my truck and the transmission has never been serviced. I'm not having any problems with it but am wondering if I should have it serviced. I'm a little scared to have it done now since years ago, I had a transmission serviced on a car and afterward it started slipping and I had to have the transmission replaced. Don't fix what ain't broke or have it serviced?  |

Hey Juan, if your going to do it, I would take it to the dealership, just in case, make them responsible...I personally have never had that done...I do know that Chevy recommends that you do the rear end after a certain amount of miles, never heard of the transmission being done, or at least I never have done it.

Ha! "Make them responsible". Try to hold a dealer responsible. They are more slippery than an aroused eel.
I have 3 Ford Expeditions (long story) that I tow with. They have 300k, 275k, and 170k miles on them and they have all had their transmissions serviced. I use a local guy who struck out on his own after becoming disenchanted with dealership practices. He's always shot straight with my wife and I and we've paid him a lot of money over the years.
It's kind of like, "Well, my truck has been running fine. Maybe I don't need to change the oil." What???

The Dodge dealership here is a rip off and they charge 10 times more than a repair shop would. They've ripped me off before and I refuse to go back there so the dealership isn't an option and I have a good mechanic shop that I use now any way. At what intervals did you have your Expeditions serviced? I've read that some transmissions don't require serving and my owner's manual states that it should be serviced at 60,000 only if the vehicle is used for police work, taxi service or frequent towing but since it's 35,000 miles over the 60,000 mark, I'm worried a fluid change might cause the transmission to start slipping. |

Hmmm... I can't say that there have been regular service intervals other than for oil. Oil has always been 3,000-3,500 miles. I'll do transmission maybe every 3 years or 50k miles or so. About the same as I'd do my coolant flush, rinse and fill.
What about a fluid change would make things slip? I guess I've never considered that (ignorance). Sounds like it hosed you.

What about a fluid change would make things slip? I guess I've never considered that (ignorance). Sounds like it hosed you. All I know is what I've been told and what happened when I had the fluid changed in a Olds 442 (that was way overdue for a transmission service) I used to own. When they changed the fluid, it caused the bands to slip inside the transmission. I was told that the bands were "conditioned" to the old fluid and the new fluid was cleaner and slicker so the bands slipped and I had to either have the transmission rebuilt or buy a new one. I elected for the new one since there wasn't much difference in cost.. That's what I'm worried about. I trust my mechanic shop so I'm going to talk to the owner tomorrow and get his opinion. (He also has a Dodge truck) I honestly think most services are required way sooner than they need to be. Especially oil changes. I think the oil companies just want to sell more oil. I change my oil myself every 7,000 miles and that's even before my truck tells me it's time. I've seen oil that claims it lasts 15,000 between changes and Mobil-1 oil claims it lasts 100,000 miles. I used to change antifreeze every two years.. no more. The truck's owner's manual says it's good for 100,000 miles so I'll change that soon but it probably doesn't need it. The spark plugs have never been changed either and it doesn't miss a beat but with 95,000 on the truck, I'm going to change those soon too. It's messing up the transmission by changing the fluid and filter I'm worried about. |

Yeah, there's a big difference in today's transmissions and an Oldsmobile 442 I'd change it at 100k as a reward for getting you there!

I completely agree. However, I have several vehicles that average a quarter million miles apiece service life and they are still going strong. Got to be something to that. It may come down to how long you plan to own that truck. If you're not going to keep it much longer, blow it off and let the next owner throw the dice on the transmission service. |

I don't plan to get rid of it any time soon. I've added a lot of gadgets and done a lot of stuff to it and it still looks almost new so I'm keeping it unless something major goes bad on it. It's 10 years old now and my wife keeps telling me to buy a new one but I'd have to add a bunch of stuff to a new one on top of a new truck payment. New trucks cost more than they're worth (at least to me) these days... I priced a new GMC at almost $60K. New trucks ain't cheap!!
I talked to my mechanic and he said he'd be happy to service the transmission and it should be fine but if it were his, he wouldn't worry about it since the existing fluid isn't burnt and not many people have their transmissions serviced these days so I'm going to let it slide and just get new antifreeze and plugs installed.

Yep, a transmission shop or a shop with the right equipment is probably going to be the only places that can do it right since I'm told you can't get the fluid out of the torque converter without a special machine that can suck it out, so a service anywhere else is only going to get out less than half of the fluid but changing the filter and changing some of the fluid has to be better than not doing it at all. I have a cooler in front of the radiator too but I'm not sure changing part of the fluid and not replacing the filter would help much. |
