... transmission fluid. I have an '07 F250 with Torqueshift transmission that calls for the fluid and filter to be changed at 30k mile intervals. The shop wants to flush the fluid but I'm a little apprehensive about that based on past experiences and some horror stories about the process. Are those problems now nonexistent or should I just have the fluid drained, put a new filter on and fill it with fresh fluid?

 

I would rather just drain with the pan screw then to have the system back flushed. Every vechicle I have seen the flush done to has some tinny noise or other issue that was not there before the flush.

 

If the shop you're referring to is the dealer, it'd be ok IMO to let them do it. Personally, I always did my own. It's a pretty simple job that you can do on your own and save yourself a little $$$. The only problem is you won't be able to get all the fluid out at once without the flush.

 

So if one was going to do it them self all you have to do is pull the drain plug and refill with new fluid with the same amount that came out?
Or drop the pan and replace the filter too?
They have two filters right. I havent done mine yet im right around 30k miles.
Thanks...Gage

 

They have a thermostat in them that opens and closes to allow flow, that requires a hot flush to do it correctly. We get both our T-shifts done at the dealer, never an issue costs in the $300 range, maybe $400.

 

There is no filter in the pan, it is just a screen!

A good idea is to change to a 2008 pan and filter, 2008 and newer trucks do have a filter instead of a screen.
