Ok i got the tranny in the truck early today and man does this thing run like a raped ape!(hope it lasts) But ive got a problem with my vaccum line, should it be hooked up to the port on my carb or an intake port?

 

Manifold vacumn not carb vacumn

 

That something I've Never Heard I've been using Mercon III for years. Please tell me more about this.

 

Ok...got some problems with the rebuilt tranny.

1. Wont shift unless you let off the gas(very slitly)
2. Wont downshift at slow speeds unless fully stopped.

Other wise it kicks ****, when it does shift the shift kit really pulls you into the seat.

Any body got any ideas on my 2 problems? Thanks

 

I replied to your other thread.

 

Sounds like a sticky governor to me. But, check the vacumn to the modulator but that wouldn't cause a no downshift.

 

I had the same symptoms and it was simply an adjustment issue with the vacuum modulator.
