Re: 5R110 issues after fluid change ? Fluid change tricks ?
Yes, you're being paranoid. New fluid can only help a good transmission. It can't fix a broken one, so if the trans is dying new fluid isn't going to save it.
On a Job 1 truck you have a filter in the trans cooler line. It's important to change that filter. The internal filter is good for the life of the trans,
Only use MERCON SP or MERCON LV fluids.
