Tranny flush?

[northernstroker]

I was going to take my 04 to have the transmission flushed at ford and am not sure the last time it was changed. I bought the truck with 84K miles. Truck has 106,000k now and the fluid looks and smells fine. Is it safe to change it??

I would do a fluid and filter change, not a flush. Dont bother with Ford, they will overcharge you. Find a reputable transmission shop and have them do a service. Make sure they only use Mercon SP, and dont forget about the frame mounted filter on the passenger side frame rail.

Torqueshifts are supposed to be flushed every 30k. You can do a drain and fill, but that only changes 45% of the fluid. $300 tranny flush, or $5,000 tranny replacement

So when are you supposed to change the filters? Flush a trans at 100k and you will be spending the 5K on a new trans.

Not sure what the records are. The fluid looks and smells fine,but would like to do any preventitive maintenance I can.

What was your dealer going to charge you for the flush? I would still do a flush, if the fluid looks and smells good, and it shifts good, just be sure htat whoever does the flush uses Mercon SP or something compatible like BG synthetic
