I think my fluid is a little low, looking for what i should use top it off. I am currently running synthetic, what should i get? Thanks for the help

 

anyone got any ideas, want to pick some up tomorrow, thanks again

 

DTT recommends +3 or dexron.

 

I've ran both amsoil synthetic and now I've been running dextron/mercon. I would not mix fluids.

Find out what you already have in use.

 

alright thanks for the replies, I am wondering what Mass Diesel put in there when they serviced it, i know that it was synthetic, maybe it will say on my receipt, thanks again

 

I just looked at my reciept and all is said was synthetic AFT fluid, how many kinds of synthetic ATF are there? Thanks again

 

Any synthetic ATF will be fine. There are no complications adding 1 quart to top it off.I know Scott used to use amsoil.....

 

What does DTT do to a trans the warrants the use of Dexron versus the stock ATF +3 or +4? Just curious.

I'm a manual guy, so this doesn't affect me, but I'd like to know.

 

Bill K. will never tell. I think it has to with the clutch material they use in their rebuild kits.

 

ATF 4 should be used using dextron makes the clutches bite harder but also wears them out faster and ATF 4 can handle hire temps the best thing todo is use lube guard automatic transmission protectant with you trans its $16 a bottle but works miracles www.mlsna.net carries it. we have 3 trucks 47re trans with 300+ k on the trannies all factory original trannies no issues and all of them are trailer rigs

 

There in lies the problem with your recommendation. A DTT tranny is not a factory original. DTT specifically recommends +3 and NOT to use +4. They also state NOT to use any modifiers or additives in the oil without first calling them for approval.

 

I topped mine off with a Quart of Synthetic ATF +4, I was told that +3 was no longer made and that the ATF +4 replaces +3

 

Same here....no ATF plus 3...only 4...and now it's synthetic...

 

Look at the ATF on BullyDogs website. Looks like might be good stuff. I may run it after I rebuild my tranny and some of ya'll do my field testing
