sensor may be out..

run fault codes and check for cam/crank position sensor failure.. Check that the cam shaft is actually turning and that the belt is not broken. Check immobiliser for proper operation.

No, The timing belt drives the water pump and camshaft.

output speed sensor on the transmission is bad.easy to replace

Does it appear to stay in lower gear too long before shifting up when driving or any other symptoms?

you can have to replace Gasket, bolts, o-ring in other words, replace it and buy it a kit for this section go to www.advanceautoparts.com and get it God bless you

code p0700 refers to transmission control system/MIL --malfunction===causes --wiring ---TCM (1)code po740 refers to torque converter clutch (TCC) solenoid--circuit malfunction===causes--wiring--TCC solenoid--ECM/TCM (transmission control module) (again) code p0871 refers to transmission fluid pressure (TFP) sensor C -range/ performance problem==causes---wiring--poor connection--TFP sensor--ECM /TCM (yet again)code p0734 refers to gear 3 ratio (po374 is gear ratio 4) incorrect ratio===causes --wiring--TR sensor/switch--shift solenoids--transmission mechanical fault (causes are the same for po733&734) code po846 refers to transmission fluid pressure (TFP) sensor B-range/ performance problem===causes ---wiring--poor connection--TFP sensor--ECM/TCM (again). Give the clutch a miss as you still have 1st gear and if the clutch is not working you will not be going any where. Have a pressure test done on the transmission to check for internal mechanical failures (pump ). The rest are sensors are wiring connections , sensor and TCM. My bet is the TCM unit. Have it checked out. What ever you do treat any suggestion of a new transmission with a grain of salt until you are shown proof positive that you need one.

buy the reprogrammer

you could have a vacum leak some where in the system that can cause high rpm,also if you have a bad tps(throttle position sensor) it can cause this type of problem.you don`t say if you have check to see what is turning on the check engine light and what code is in the computer.this should have been done and may have help to find the problem in the begining.

assuming you have already checked the bulb, make sure where the bulb fits is nice and clean. if the light does not come on with the door open its likely the door switch that is dirty and needs to be removed and cleaned so it gets good ground. this switch is usually found on the door frame and will have a rubber cap over it. remove the cap and unscrew the switch and clean it

Once having checked the oil level and made sure it has the right grade in it, if the engine is not rattly or making knocking sounds this probably is not a worry, as long as the light never comes on when cruising.It is possible the oil pressure sender is faulty. You could find out more by removing the sender and attaching an oil pressure gauge to see if all is well at higher revs.Here is a wise comment on Harley oil pressurehttp://www.fixya.com/motorcycles/t9320147-low_oil_pressure

run fault codes and check for cam/crank position sensors fault. Check that the cam is turning as it may have broken a timing belt.
