hi all............
iv got a 93 s10 4.3 w motor....with 145k
runs purrrfect........allround.
the funny thing is....when i use the cruise....and set it to 65-70.
it will loose about 10 mph goin up hills.
iv had many cars with cruise and never had one not keep the set speed.
some input would be much appreciated.

Will it downshift at all?

it does d/s i think ..but,,,,,doesnt seem to be enough unless i help it a lil .seems like i need to give just a lil more throttle to get back to speed.

You think?

it does seem to d/s but not enough to make it accellorate like it would if i step on the gas my self.
it goes up the hills fine...when i dont use the cruise.
thats why im askin for help.
i would think it was the tranny...if it did this while not using cruise.
but again...this only happens while using c/c.

The cruise control i svacuum operated.

Make sure the vacuum lines going to the vacuum ball under the hood are leak free and connected properly.
