INEEDAGN said:TRANS-X!!!!!!! you have got to be kidding me. That crap is bad. Real bad. We would rather not work on a trans that has had that stuff in it. It ruins everything. AND, when you get that crap on your arms, it reacts with your skin and causes bad rashes. Chryslers break because of simple crap, broken snap rings, valve body warpage, diff pins coming out of the carrier, etc. Cross leaks happen but trans-killer is not the way to go. You won't find it in any trans shop because they all know how worthless it is. Some shops (and this is no joke) charge people extra if they put that crap in.
As far as Chrysler VS. GM trans, up here all the farmers (who are mostly chevy lovers) Think they can pull the worlds longest stock trailer with a 1/2 ton pickup and leave it in OD from here to Texas. We do lots of low mile 4L60Es. Guess it depends on the region.
I will agree,that some cross pins do come out of chrysler mini vans overdrives..i;ve seen maybe 3 do this,they make a retainer kit to prevent this
If you don;t like additives,don't use them,but for me, it works great,and it goes in every single chrysler we sell. and we don't get them back for trans problems....BTW 4l60E's...are in my opinion junk..we do have alot of those go bad, usually due to wear in the TCC switch valving..too bad..they use it in all most all GM trucks
