Answer -
Larry,

I see you have a 68 with an early AOD in it. So, when does it shift into od?

Answer -
Do we have two threads going? LOL

Answer -
Hi Larry,

Did you try the gov yet?

Answer
Jeeeezzzzz, Thought I answered this at work already. I suggested in one of the strings we had going that you should try replacing the governor. It's an easy install and about $40 from the dealer. This should bring fourth back into a reasonable shift point. I killed one of the threads so just answer this one. Let me know after you get it installed and road tested. Sorry about any confusion.
