this is a very general question and could be a number of things, if both your engine and transmission behave poorly together the first place to look would be your air filter, see if it is clogged or old and possibly replace it with a performance type like a K&N brand filter. If you have problems accelerating quickly, if there is a sudden pause or stumble in power when you floor it, check the mass airflow sensor if your car has one, it is a small tube sensor the air flows through between the filter and intake, and see if it's small wires are dirty, they can be cleaned carefully with alcohol. This makes a huge difference on 94-96 LT1 engines. If that does not improve things try changing the fuel filter, sometimes they need to be replaced much more often than the suggested 30,000 miles. And finally sometimes the Chevy v8 although big and reliable is not always that strong, and you may be stuck with a weak stock engine.
The same thing happened to my dads 96 Chevy S-10. The transmission was rusted not allowing it to shift. I would have the transmission checked out.
If your 1997 Chevy diesel will not shift into overdrive, you might have an issue with a transmission sensor. Some of these vehicles have several sensors that must engage in order to shift.
No shift at all.
Shift solenoids are located inside the automatic transmission, accessable via a side cover plate.
vacuum leak?
67, to 69 Camaro will bolt right in.
My 1997 would not shift out of first gear, was 'throttle position sensor'.
Yes it sure can.
Transmission trouble
Yes they will fit , But you will notice no change what soever. ( no more power )
The aggregate demand curve will shift to the right as the economy expands. When that happens, the quantity of output demanded for a given price level rises.
could be linkage adjustment or low fluid level in gearbox
