Auto Transmission Shifting Issue Since 4bbl Upgrade

Well it's a pair but they're connected in the same place. They do that "in case" one breaks. But yes, that's "just" the throttle return spring. THe other spring is eliminated with the cable kit. I thought it was.

The factory cable setups used in throttle body efi vans and trucks uses a spring on the transmission. Because it is a cable it needs to be pulled back. It cannot be pushed back from above.

BTW, this is a far superior setup to the lokar bicycle cable style, can be easily adapted to an older carbureted Mopar, and is what the other aftermarket cable set up (I forget who sells it) is based on. Factory parts!

Not to add another A hole's opinion to the discussion, buuuut,:D
I added a light spring to the TP lever on the trans though the directions did not say to do so.
The reason is that sometimes the lever does not come come fully forward, but only to the point the spring behind the TP valve in the valve body makes it move.
There is a bit of freeplay after the internal spring is at it's full travel and the light spring on the lever at the trans returns it fully forward every time the throttle is let off.
Otherwise there can be a slight variance in the TP at very low throttle openings causing your really low speed shifts to change.
It's really not a big deal to not have it though.

This is what the return spring on the factory rods type linkage does, as RRR mentioned.
That and it helps counter the weight of the factory rods themselves.
