hey guys i am looking at having my 110xxx mile trans. rebuilt with a zzp shift kit added and was thinking about putting Royal Purple max atf or some kind of dex VI in it, so what is your guys opinion which should i use?

 

dex vi is supposed to be really good. but i have heard alot about royal purple stuff tho

 

I would stick with Dex 6.

 

I do feel like the synthetic fluids are far superior to anything organic myself... Royal Purple is good motor oil for me, I use it in both of my cars. I would consider their transmission fluid on my next flush.

 

Dex 6 is a synthetic blend, I just feel that if something gets completely GM spec'd and certified, why not use it?

 

Thought is was full synthetic...but either way...as of right now...I would say stick with Dex 6.

 

I only use factory specified fluids in my transmissions, whether it's for my Ford, Chevy or Dodges.

 

i looked into royal perple trans fluid it only covers dex and mercron IV not the VI. i am looking into it further but i havent had the time yet because i have been really buisy lately. i would use the dex VI till you find more info on it but i am looking but didnt have time yet

 

i use there gear oil and motor oil but looking for more information for the trans to make sure i wont mess it up

 

just looked it up gm part number for dex VI is GM 9986195 looks like it covers it i am glad. it looks like it is set up for a up grade for alot of fluid that calls for a lower fluid then dex VI and excells it looked it up on other site. that i got responded to some of the guys that are there are trans builders they said it is a better choice but they said dont go back to the reg synthetic blend. because it will put a strain on the pump in the trans if you go full synthetic like royal you pretty much have to stick with it. like going with synthetic engine oil where we have to stick with it because the oil pump is use to the slicker oil. thats what i have been responded to as well as some trans shops told me this morning i was going to have them do a service drop pan put inthe up dated one with the nut and new filter.
