My daughter drives my old 2000 Chevy Blazer with a reconditioned transmission I paid for in Aug 2010. The new (rebuilt) transmission is now slipping. Could this be as simple as a fuse (electrical signal issue) or not having enough transmission fluid? ---

Yes. Check the transmission fluid level. Low transmission fluid level can cause slipping. Tester ---

How many miles on rebuild? It slips in all gears? Or just a few? 3-4 clutches are weak on those trans. ---

I think around 60000 miles on the rebuild. I don’t think it is slipping in all gears. Just a few, not all the time. ---

This is why some people walk away from a car once the transmission fails. Rebuilds are only as good as the skills of the rebuilder. 4 years and 60,000 miles is actually not terribly bad for a rebuilt unit. Especially a complex unit like that one with known weak points. ---

@transman618 used to recommend using Berryman’s B12 Chemtool in a dying transmission. I’ve used it and it really works. Hard to believe but it really does. Just add 1 can to your transmission. ---

to Busted knuckles: yes…but on the advice of the car talk discussion at the time, instead of trading it in, I paid for the rebuild. My daughter’s car died shortly after that so I gave her the Blazer and bought a new (used) Honda CRV with no trade-in. She’s had it maybe three years…so I saved myself having to get another car for her at the time. to Missileman - I passed on the info to my daughter. Thanks! ---

It could be a clogged transmission filter also, try a fluid and filter change first.
