Please first understand that this was on a stock transmission
A DTT setup may act differant.
I tried the Amsoil Universal ATF...
Did the change... and proceeded to have the worst shifting transmission I've EVER driven.
Shifts were SOFT... shifts should feel FIRM. . these were SSSLLLLIIIIDDDDEEEEEEEE.
I could practically hear the transmission waving "Good Bye!!!"
I drove with it for 2 days. . and said NO WAY!!!!
I even bought enough to do another change in 1000 miles because I couldn't get the TC to drain easily.
I sent the whole batch STRAIGHT TO HELL VIA THE PLANT INCINERATOR!!!!!!!!!
I went to Dodge and got the "New" Atf+4 (it superceeds all other for DC useage)
This is a Semi-Synthetic.
It looks and SMELLS differant...
A DEEEEPPP ruby red. . and kinda smells like plastic.
After 2 MORE changes... . with the new dodge stuff...
I can say that the transmission now feels better than the day I bought the truck!!!
I'm also looking and saving my money for a full DTT setup. . and I will heed the advise of Mr. Kondolay on what ATF to use. .
But for a stocker... I couldn't find a better fluid than the ATF+4 From Mopar.
Just my 2 cents rounded to the nearest nickle!
