92 F250 with 106,000, tranny has never been serviced to my knowledge, to change or not to change the fluid and filter is the question?? Let me know what you all think!!

Thanks

 

Change both the fluid and filter. Don't have a power flush done at one of these quicky lube places. On a 14 year old truck there's bound to be junk inside that transmission that doesn't need to be moved around. At least drop the pan install a new filter and refill. Repeat every 15-30K. If you're able to drain the torque converter while the pan is off that will get more of the old fluid out. Either way, fresh fluid and a clean filter may improve the shift quality of the transmission and add to its life.

 

Yes, just do it yourself. Drop the pan, turn the TC till you see the plug and drain that, and then change the filter. Have two cases of mercon on hand.

Will do!! Thanks!! BTW any preferences in fluid??

 

I like motorcraft Mercon for my 4R100 (basicly the same unit as your E4OD).

106k and never been serviced wow! you are lucky that thing isnt slipping like crazy. a fluid and filter is all you should do. flush is risky. might dislodge some junk make things worse.

 

How do you get the fluid back in the TC? I know stupid question. I know how to add fuild but if the TC is dry and the pan only holds 4-6 quarts, How do you add all of it back in with out runnig it dry? I also know my truck doen't have a drain since it's an 05. I just wanted to know, Thanks.

 

Fill, idle for a minute, fill, idle for a minute, ect... Till you have the amount in that you took out.

That doesn't hurt anything, running it without any fluid in the TC?

 

Thats the same instructions I got from my tranny shop this summer when I put a new TC and Tranny in my Charger!!! Worked like a champ!!

 

No, it won't hurt it.
There is no other way to fill the torque converter.

 

I mean, don't put it in gear and try to move, but unless you unbolt the trans, take off the TC and fill it manually, there ain't no other way to do it.

the pump in the tranny will fill up the converter. turn the truck on. pour a few quarts in go thru all the gears, add few more quarts. go thru all the gears, few more quarts go thru gears again. keep repeating that. dont drive it doing this. hold the brake whie going thru the gears. after about 10 quarts start driving slowly. few more quarts.drive little more. you will be able to fell when its right. just keep checking the dipstick

 

A few things to Add, Don't start the engine with the Tranny dry. First, stick your long neck funnel in the tranny filler tube and pour in 4 quarts of fluid in the tranny, THEN start the engine, then add more fluid while the engine is running (have the bottles of ATF ready to pour in with the caps off). When it gets near full (over 10 quarts, hold the brake, move the selector through the gears, add a quart or less of ATF, check the fluid level with the dipstick, keep doing this until you reach the proper fill level. Don't overfill.
E.D.

 

hes right put a few quarts in before u turn it on. thats a good time to check pan gasket also.dont want to be under a running truck if you dont have to be.
