Hello, I have a American pickup 1995 American 6 automatic cylinders 4.3l TBI and the problem it presents is from the first change to the second since it does so between 2000 and 3000 rpm (that if it does soft not with a pounding), the others perform them softly and norrmally. The probma was presented when I sent it to refine it to clarify that the transmission adjusted it a year and a half ago and worked very well, only that when the oil was already thick and dirty, yellow and olia a little burnt.
He scares an additive for transmission and improved a little. He will lack more additive or suggest.
It is worth mentioning that the mechanic told me when I gave me the truck after the tuning that would have to change the oil for a month to be clean since the one who brought was very dirty, at this time I have 3 weeks with the truck.
What do they suggest? I add more additive or what to do?
Thank you
