should i do anything to my tranny??

[lhsnbsaoa]

i have a 2008 F250 with about 142,959.2 miles on it. i just did a 3 inch lift and it has been tuned etc for about 6 months now. i bought the truck at 120,000 miles and i am assuming that nothing has ever been done to the transmission. is there anything i should do to make sure it is doing good? fluid change? filter change? anything?? seems like it slips once every couple weeks but from research i think thats just the tuner making that happen. any input would be great. thanks

transmission should be serviced every 60k. filter and fluid change. I know a lot of guys will say to have the dealer flush and service it, but I like to do as much as I can and have never had an issue doing a filter change with drain and refill on my vehicles.

The previous owner towed a gooseneck. But overall it shifts good. I've never done servicing on the transmission. Can you tell me real quick how I I about changing the filter and draining the fluid?

drain the pan if you have a drain plug, remove the pan and clean it out. Swap the filter out and put the pan back up. Easy process! Will will be right there once you drop the pan.

If you want you can get a extrenal tranny filter to help out. I have almost 200k on my truck and about to do one. Thats a good looking truck that you got there

What ever you do DO NOT HAVE IT POWERFLUSHED. Simple tranny fluid change only.

Now, if you know for sure the tranny was serviced like it should, then a powerflush may be ok, but having learned from experience Ford trashed the transmission of another truck I had after a 100,000 mile powerflush. The thing slipped bad after that. I had to trade the truck.

Good luck with it.

I have no service records up to 120,000 when I bought so I figure the best bet is to ASSUME nothing has been done.

One last question is what type of fluid and how much?

Thanks!

I stopped by the dealership yesterday to get a quart of tranny fluid and they gave me motorcraft mercon LV. Also it says to use only mercon LV on the dipstick handle
