Pedal slipping pedal cranks slip at every revolution

check the chain if it was left out side the chain could be rusted and not bending orond the sporkets

does sound like slipping clutch , you may not get all the symptoms at once , the slipping usually starts first then the hard gear change etc cant think what else it could be , may have oil contamination on clutch plate this would cause the slip , crank seal ? i think your going to have to drop the box and have a look keep me posted if you wish

Here is the definition for the code.

P0736 MITSUBISHI Description This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes
Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

Kneelnext to the left side of the elliptical's base. Use the Phillips screwdriver totighten the two screws located in the center of the left pedal.2
Use theAllen wrench to remove the bolt securing the left pedal arm to the pedal legand body arm. Use the Phillips screwdriver to remove the screw securing therear end of the pedal leg to the crank arm.3
Pull theend of the pedal leg free of the crank arm. Wipe the crank arm clean, thenapply a fresh coating of machine grease or silicone lubricant. Replace the endof the pedal leg back onto the crank arm and use the previously removed screwto secure it back into place.4
Join thefront end of the left pedal arm to the ends of the pedal leg and body arm. Usethe previously removed bolt to connect the pieces together.5
Move to the right side of the elliptical and repeatthe above steps on the right pedal arm

if it wont crank over im thinking that maybe the clutch pedal damaged the clutch safety switch under dash near top of clutch pedal stroke-prevents you from starting engine without foot on clutch pedal.

You installed the belt with the crankshaft 180 degrees out of place. It is very unlikely that the belt slipped, unless there is internal damage in the engine.

That means that the belt is worn and is starting to slip. You need to replace the belt. Here is the belt you need and a manual you can view with instructions:

i have the stairmaster 4000pt which was bought new in 2003. in 2007, i started experiencing the same problem, the right pedal would sometime slip and fall to the floor. i called the local fitness store and they came and replaced the hub assembly and that resolved the problem until now. The left pedal is now slipping.

Is it a standard or automatic transmission? If standard, your clutch may be slipping. While driving down a straight road, push the brake while still in gear and push the gas pedal as well. If the engine slows with the vehicle, the clutch isn't slipping. If the engine speeds up while the vehicle is slowing down, the clutch is slipping.
If it is an automatic, check the transmission fluid. You may be low and the transmission is slipping while under load, or the torque converter is slipping for the same reason. You may have a bad torque converter clutch switch, but the computer should have picked that up and made your "Check Engine" light come on.
These are the main reasons you would be losing power going up hills unless your engine isn't powerful enough to handle the larger tires on extreme hills. (It takes more power to turn a larger wheel going up hill since the vehile has to travel further for each revolution of a larger tire. Incidentally, have your speedometer checked. You will be going faster than what the speedo says since you put larger tires on.) Good Luck.
