Manual calls for 10 qts. of Motorcraft Mercon (ATF).

 

Most Ranger automatics use about 10 quarts, more or less, depending on the exact application. However, manuals like his are closer to 3 quarts. Mercon V can be substituted for Mercon which has been discontinued by Ford.

 

I switched to Syncromax at around 60K miles on my Ranger because the shifting was not as smooth as I prefer it. I noticed with the Syncromax the smooth shifting came back and I was very happy with it. After about 60K miles on the Syncromax, the shifting became not as smooth again. My experience with synthetics is once you switch to it you are good to go for a very long time. I let it go, thinking the trans was just getting slightly worn.

I am getting ready to tow my race car round trip from So. Cal. to Wisconsin and decided to change the trans fluid. I went with Syncromax again and immediately the smooth shifting came back. It looks like with the way I use my truck, I need to change trans fluid every 60K miles, synthetic or not. I suspect this kind of change interval (or sooner) would be good for all manual trans Rangers (with the Mazda trans).

 

Just ordered 2 quarts of Redline MTL and 1 quart of Redline synthetic ATF Both quarts of the MTL will be used, the ATF will be used to top it off--I expect to use about 1/2qt. Hopefully it does wonders for the notchy 166k mile transmission.

 

I switched over to the MTL last Saturday and now have about 400 miles on the fluid change. The transmission shifts smoother now than it has since I've had the truck, even in sub 20 degree weather it shifts great. If I were to do it over again I would have used straight MTL since cold weather shift quality isn't an issue. Great fluid, the Syncromax was a nice improvement over ATF and the MTL is a nice improvement over the Syncromax.

 

i was having the same shifting problem as other people

i may get flamed for this BUT!

i had the mechanic add 2 bottles of concentrated duralube to the tranny fluid , within minutes i could shift between the gears with 1 finger , it was that smooth , the duralube made a BIG difference

 

I have used royal purple pennzoil synchro and valvoline maxlife. All seemed to perform just as well as the other. I just put maxlife in again, cheap available everywhere and works fine.

 

I switched out my fluid in my 04 Ford Ranger Manual Transmission to Royal Purple Syncromax because I was having a hard time getting it into gear sometimes. The syncros were shot. It improved it just a little but as I drove it the better it got. After about 300 miles it shifts real well. I am very happy with the result. I have been dealing with this shifting problem for years. I am very happy with the results. I poured it through the top at the stick shift. Worked real well.

 

What is the capacity (in quarts) for the 5 spd manual trans. Mine is a 4 cyl lima 1994

 

5.6 pints, 2.8 qts (U.S. quarts) total capacity

 

in my 94 with 117K Changing it today to Royal Purple. I will post if it improves or not. Thanks for the reply. I bought 3 Quarts of RP at NAPA.

 

Best thing I could've done. Shifting is like a new truck. no more sticking and forcing the shifter. All gears are improved as well. The guy that changed it drained the old fluid then filled with a cheap synthetic and ran the truck for 10 miles. Then drain the cheap out and put RP in.
