Service Trasmission, is it due?

[prg333]

Last time I had my transmission fluid drained and a new filter put in was in 8-2008 at 76,000.00. I now have 151,252 miles on the old girl. The fluid does not look or smell burnt. Still looking clear and light in color.

No problems at all with shifting

Just as PM should I have the transmission serviced (fluid drained new filter put in)

How often do other Marauder owners take care of this service?

Thank you for the suggestions

Take it to a place with the flush machine so that all 16 quarts is replaced. A new filter is always a good idea.

I would go ahead and have the fluid exchanged and filter changed.

I'd simply drop the pan and exchange only that amount of Mercon V fluid. I'm not a fan of "flushes" at all. While you have the pan off, inspect the filter inlet. If it is free of debris, leave it alone. It wouldn't hurt to put a new one on, however that's not always needed. Also clean the pan magnet and wipe the surfaces off with paper towels to remove clutch material.

I change my fluid every 20k roughly, but only one pan worth. I do not flush or replace all of the fluid at once, except when changing trans parts. 220k on my supercharged Grand Marquis with all the original trans internals still and 106k on my supercharged Marauder with its stock tc as well. Changing fluid is a key factor to the life of the transmission.

I would leave it alone. Theres a chance by changing it at this high mileage it will cause the seals to leak resulting in a rebuild.

If you have a drain plug in the pan, drain the pan every other oil change and refill.

I'm liking the visuals with this one, :lol:

If you don't have a drain plug in the pan now is a good time to get a new pan or install a drain plug in the existing pan.

Unhook the transmission cooler line, extend it into a large bucket. With the car idling dump fresh fluid into the transmission fill at the same rate. Once the fluid comes out looking brand new, stop. When I did that and a filter swap at 65k my filter looked brand new. I only changed it because I'd already bought the replacement. Unless the transmission is doing something really weird I wouldn't worry about the filter.

The single best thing you can do to prolong the life of an automatic transmission is keep fresh fluid in it. Just because it doesn't "appear" bad, the additive pack can still be depleted.

I do agree that installing a drain plug and doing a simple drain & fill every 15-20,000 miles is an excellent way to keep the fluid fresh. Assuming the filter was replaced at least once, it's not necessary to change it again, and here's why: The majority of wear material in an automatic transmission occurs withing the first 10,000 miles or so from new. It's this material the filter is designed to catch. After that initial change, there is so little material generated that the filter is almost unnecessary, so changing again as part of normal preventative maintenance is not needed...only if the transmission is being services for a failure or for fluid contamination.

If you've already changed out the filter and you find alot of debris on it now.... your in for a tranny rebuild.

Because you went 75k between services, I recommended the flush. If you drop the pan and install the 5 quarts every 10k or so, you don't need to do the flush.
I went with an aluminum B & M pan that holds 2 extra quarts, so a 7 quart exchange is required for me.

That "old wive's tale " cost me a lot of money. I bought a used car and had the trans flushed. "Junk" that was sealing the seals came out with the flush resulting in a leak and burnt trans.
I know the trans shop that rebuilt it. They are the ones who came up with the diagnosis.
Who knows how long it would have lasted, a day, a month or a year. One thing is for sure it lasted a week after the flush.

[RF Overlord]

If there was that much "junk sealing the seals", then that transmission was already bad.

This is on my to do list...
