It really has to have a scanner on it to tell. But here are some things you can try. The OD button is in the off position. Try cycling it as you drive. The light could be bad and you don't know it's off. put the shifter in first gear position, up shift manually. Does it go from first to second? Second to third? You could have lost a gear. Usually first. Usual sign for this is no power take off/sluggish. All of these would throw a code. Some wont turn the check engine light on. Again a scanner is needed. Basically the toque converter clutch solenoid is not engaging..Could be internal problems... Dirty and/or the solenoid is bad.

No steering no brakes/brakes are hard as a rock so is turning the wheel.
Replace Power Steering Pump, seals are blown. As for your brakes, lines need to be bled and adjusted. When bleeding power brakes DO NOT Bleed While Engine Is Running! Doing so will result more problems. Suggest it be done by a certified mechanic at a brake shop such as Pep Boys or even Midas. If brakes are still hard then it may very well be your hydraulic pump ( big circular object connected to the brake master cylinder on the fire wall ) is no longer functioning and must be replaced (rarely happens but....)

I lost spark on my 2001 chevy 3500 with the vortec 8.1 motor. what can i try?
Go to Autozone.com and get a free wiring diagram by registering your truck. They also provide fusebox layouts. Some GM units use Relays for the Ignition.
You should be able to trace the power from the Ignition switch, through the Relay and out to the ECM. Then it is a matter of finding out where the power dies.
Now it takes a pulse to fire the spark and you should have a crankshaft sensor. Check your connections there.
Please rate my info.
