So I am having some vibration noise in Final drive. It appears to only happen with O/D on. It may be my Lock out valve in the tranny but i wanted to start by changing my tranny oil and filter and adding some additive to it. I've spent a few minutes trying to find this information out on this site. However I cant find it and the site is running slow.. (maybe my internet) The Manual says to use ATF+3... What the hell is this?
I know it stands for Automatic Transmission Fluid but i dont know or even see a +3 at the local car shops.


Any recomendations on the the oil additive? The manual says not to use any and I just purchased the Gressed lighting...

Thank you for the help in advance....

 

it is actually ATF +4 now I think ATF +3 is not on the shelfs anymore. I am actually getting ready to do the same thing.

What are sources for the ATF +4 other than the mopar brand at the dealer?


SubRoc

 

Someone said Walmart was selling it (on this forum)but I called Autozone and they also sell ATF +4.

 

Use ONLY MOPAR BRAND, Walmart, Autozone and O'reillys carries it.$$$$

 

So if i go up to the AutoZone clerks, they will actually know the type i am looking for? +4 is safe to use in a tranny asking for +3? I was a little scared to ask the Clerks because i didnt want to put my trucks life into their hands
What actually does the +3,+4 stand for?

 

Well if it calls for +3 then use +3 cauz +4 is dang expensive lol

 

The only problem is they stoped making +3 and upgraded to +4...it is the same thing just more advanced.

 

Maybe at the dealership they feed you that story, but I can buy +3 at Advance Auto Parts anytime.
That's how I know +4 costs a lot more, I just got done with the trans fluid + filter thing yesterday or day before.

Don't let them rip you off, I always get a 2nd opinion unless I trust the mechanic 100%.

 

ATF+4 replaces ATF+3.
