Tranny question?

[tnnuke]

I just bought an 02 F250, 4x4, 7.3L truck. The truck has 97K miles and the transmission fluid has never been touched. I am one of those guys that change his fluid every 30K miles, but I have been warned on this truck. I was told by a Ford dealer and several other folks that if this truck had never been serviced with 97K miles do not touch the fluid because once you flush it and change it, the tranny will fail soon after becaue of the deposits that will break loose?
Has anyone else been told this? I was hoping to put a shift kit in it but now I guess I will run i until failure and not mess with it.
Any input would be appreciated.

I really dont buy that whole dont change the fuild thing. I may be wrong, its happened once or twice, but I opperate on logic, and logic tells me that doesnt make sense.

whats the condition of the fluid?

Fluid is pretty dirty. So there is probably some deposits in the unit.
It makes sense. The fluid is mostly detergent and when you change it the fresh detergent will clean everything well and break the deposits loose that ruins the tranny.

Thats some dumb sheeeeet right there. Change the fluid and filter and get you another 100,000 miles out of it.

the deposits are what you dont want. thats what causes the wear.

Change it. If you're worried about deposits breaking loose, then change it again after a few thousand miles. Not necessary IMO, but if it makes you feel better then why not?

TN: Think about installing an external spin-on filter kit on your transmission... Like the one stealth or dieselsite sells... Take a look at Auto-Rx Engine Cleaner. very very good product. Change your fluid and drive.

I bought my truck with 260K miles on it. The trans fluid had never been changed. I had the transmission serviced. The trans is not in great shape, but it will work until I can afford to visit brian at BTS. Then I installed an external spin-filter, and poured in auto-rx.

Since then, every 20K miles i drain the pain via the drain plug and change the spin-on filter. Fill with Amsoil Torque Drive.

The trans has right at 275K miles on it now. The shifts have seem to have become a bit less sloppy. This was not a cure all by any means... I was just trying to buy more time to save for the BTS transmission.

Change your fluid and drive.! If anyones transmission was going to die, mine would have. If that myth was true.

Makes sense to me
