shuddering at 48 mph

I started to feel a shudder while accelerating at about 48 mph in my 96 Expo. It feels like it is happening as the tranny wants to shift into overdrive. Any Ideas?

Check your u-joints and driveshaft :rofl:

Already have been there. Everything is nice and tight. Going to try Lubegard Red and see it it helps.

Focus on engine performance. 1st
If the performance isn't there, it could make a good transmission look bad.

I agree, I would see if any codes have been stored in the system and go from there. Even if the light does not come on it could have still coded up...:lol2:

There are no codes stored, engine is fine. Definitely tranny or rear end. I had to order the Lubegard from ebay. Nobody around my area carries it. I've heard that this is common in Ford transmissions and the Lubegard is a cure. It's worth a try and can't hurt Anyone else ever try Lubegard?

No I have typically used BG products...It is worth a try though, would be a cheap fix if it works

Well, it seems that the lubegard Red helped out a bit. After about 50 miles the shudder seems to have disappeared. I still feel it slightly on a slow acceleration but nothing like before.
