What will happen if the wrong tranny fluid is put in a 4l60e like something for a dodge viehicle??

 

I do not know exactly but I do know that I would get it out and change the filter. I did that once and the tran. did not shift right.

 

The feel of the shifts will probably change, maybe reduced transmission life.

 

well at the track after 1st gear it goes into lock up and wont come out and on the street it runs fine shifts good and everything...it only runs wierd at the track...anybody else have any ideas?

 

While on the subject, what is the preferred brand of transmission oil and filter for the 4L60E?

 

i replaced the tranny fluid and its feels alot better...just have to see how it does at the track

 

I changed my fluid out for the generic VatoZone ATF fluid. . . . . I can not call it the "preffered" fluid but it seems to be doing well. Shifts real nice and solid and clutch packs seem to be not getting eaten up. Fluid looks real clean after about 20k. . . .
