failed relay
The bed size is 6.5' of a dimension of 78x9x5 would fit a Chevy 1990 pickup.
It turned out to be the alternator going bad. Replaced alternator. No more growling.
It would be the 700R4
The "heat maker" is broken. :(
YES, They are the same engines. That would be a direct bolt in.
A 1977 Chevy pickup truck would have rotors in front and drums in the rear
That would be the 4L60E
Probably the steering gear.
