I bought my 2.3 5 speed 2010 Ranger brand new (I factory ordered it), and I have this exact same problem, most notably in stop & go morning rush hour traffic. It annoys me a lot! As long as its still under warranty, I keep going back to the selling dealership for service,( even though I am a Brand X dealership mechanic myself), to keep a maintenance "paper trail" in case of problems while under warranty. I mention the problem every time I go back to the dealer, they always come back with "could not duplicate customer complaint". I have been driving since 1973, and have had mostly Fords with manual transmissions, 3 speed non syncro, 3 speed full syncro, Toploader 4 speeds, T5s, NP435 truck,Jerico 4 speeds in my drag cars, as well as the Ranger 5 speeds. My 50`s Fords, and my 74 F350 have non syncronized low gears, so I expect them to require some effort to get into low gear, BUT a fully syncronized trans should not require that. None of my 69-70 Mustang with 4 speeds, nor the T5s that I swapped into a few 302 Fairmonts were hard to get into gear, I can not believe that my 2010 Ranger should be.
As for ATF, almost all the BW T5s used in the 5.0 Mustangs used Dextron/Mercon ATF, and they work just fine. Most T5s use paper linings for the syncronizer material, and are designed to be used with ATF, heavier gear oil is NOT a good idea. That is fine for the older Toploaders, which used bronze syncronizers, but not with the paper, or later carbon fiber syncros. I don/t know what the Rangers trans have for syncro material, but with ATF, I bet its not bronze.
As for the older MoPar manual transmissions using ATF, that actually started in the 60s. I have owned 2 Plymouths with the A833 4 speeds, and the use of ATF was likely used to make these clunky MoPars trans shift half decently. Although the MoPar 4 speeds were very strong, they shifted like trucks compared to a Toploader. The lighter ATF made them a bit nicer to shift .
Rory, that's it exactly. Very annoying when it won't go into gear and is bound NOT to do it when you take it in. I wonder sometimes if I am taking years off of the syncro by getting mad and pushing it harder. But when I have time I'll pull it back part way into 2nd and then back into 1st. I heard that a couple of different brands of transmissions were used on the assembly line. Has anyone else heard that?
Thanks guys, Ernie
I always go down through the gears on my 06 and have no problem going into first at a stop. Have 61k on it. A Mustang we had back in the 90's speced 10w30. So a lot of fluids will probably work. I am currently running Mobil 1 ATF with no shift problems.
