transmission issues

[bootdoc]

I'm looking at a 79 revcon. The ad said the transmission had been recently rebuilt. I took it for a test drive and while on the highway it dropped out of 3rd gear at about 55 and stopped accelerating.
I pulled to the side of the road and shifted to 2. It moved moved forward fine. As I gained speed I shifted to D with no noticeable difference. Sounded like it was still in 2. I shifted between D and 2 several times as I drove it back to the sellers house. I could not hear or feel a change in gear. The owner sent text today saying it was a seal. Am I looking at possibly rebuilding the transmission? Is the seller not being honest?

Tell him you will consider After He gets the tranny repaired.

If the seller is motivated, I'm sure he would not mind paying for a second opinion from a transmission shop that YOU chose. That is the only way to determine if the transmission is faulty.
I assume that he has documentation from the shop that did the work. If he does NOT have receipts for a compete transmission rebuild, I would walk away.
He might have just had a transmission SERVICE, instead of a complete rebuild.
