So, I just bought my first PSD. It's an 01' SuperDuty Lariat. I love the truck btw.
Anyway, I just checked the fluid level and it was running warm while in neutral, and on level ground. I pulled the stick and it was just right at the lowest warm level. I figured I would add some ATF, so I went to my local Wal-Mart and bought some Dexron III
My question is:
Is it alright to just top it off with the good Dexron III, even though I have no knowledge on the history of this transmission? I'm thinking this transmission could have been redone, or replaced already because I have 198,xxx miles on the truck. I just bought it and I have no clue on the truck's history.
I really don't wanna flush the tranny fluid or really even change it for that matter either. It looks clean to start with and it runs fine, so I don't wanna mess with it. I don't want to run it low either, so is it okay just to add a quart or two of the Dexron III?????
My future plans are to add the Tru-Cool trans cooler (add-on to the current cooler). If I do this how much more tranny fluid would it most likely take? And would it be alright just to top it off then too? (Once I get the new cooler installed)???
