I had a small drip between my trasfer case and transmission on my 94 Jeep Grand Cherokee, I took it to a couple of really busy transmission shops and was advised by both they could repair for $500-$700 or I could put Trans X in to soften the seal It workedno more dripNapa said I can keep it in and not worry about it, but a friend told me it needs to be drained due to debris could now be in trannyHow long should I run before draining? I have no problem with the cost of draining and new trans filterjust need to know for sure I should do it!
If it ain't broke don't fix it. If your tranny has debris the filter screen will catch it. If the filter screen becomes clogged and needs replacing you will have problems with your car shifting or fully engaging in gear. Why spend money and time on a problem that don't exist?
But then if the trans doesnt have a filter.
Problem is those seal softeners weaken the seal even more overtime. I don't think the additive will affect the tranny but sooner or later that seals going to need to be replaced.
