96 artic cat panther 440 lc clutch slow to engage(high rpm's0

I don't know if this holds for the 95 but my understanding is that there is an oil pump in the tranny that works to keep the clutches engaged in the lower gears and it puts out a higher pressure than the rear pump. The rear pump is used to keep the clutches engaged at higher speeds because it doesn't need the sustained high pressure. The rear pump takes over from the front in higher gears. It would seem that your 'high speed' pump is not functioning properly and should be checked.

PO 440 is a common Evap System Code

Article 96-26-21 is being republished in its entirety as part of a consolidated 7.3L diagnostic aid booklet.
ISSUE
Some vehicles with transmissions built prior to 11/13/95 (5L13) may exhibit a driveline resonance/vibration between 1400 and 2000 RPM with the torque convertor engaged. This may be caused by the torque converter.
ACTION
Prior to torque converter replacement, refer to the following Service Procedure for details to verify conditions.
SERVICE PROCEDURE
1. Verify the resonance/vibration does not occur in neutral and is most noticeable between 1400 and 2000 RPM with the converter clutch engaged during medium to heavy throttle conditions. Also watch for the vibration to diminish at engine speeds lower than 1400 and higher than 2000 RPM. If the concern meets all of these conditions and the transmission has a built date prior to 11/13/95 (5L13), replace the torque converter. Refer to the appropriate Service Manual for removal and installation procedures.
2. If the vibration concerns do not meet the conditions, check for non-factory installed items that could affect driveline and verify proper installation. Also refer to the appropriate Service Manual, Section 05-00 for diagnosis and testing.

Hi!

When a car is in gear with the Gas pedal pushed down, the engine RPM is high so the oil pressure is high too that means the Sending unit is detecting high pressure. But when you engage the clutch that means the gas pedal is released so the RPM drops and the pressure drops down too. So all i can say is that you might have a bad oil pump that needs always high RPM to keep the oil pressure normal.

Good luck

sounds a lot like the throwout bearing is binding on the input shaft and not releasing the pressure plate. In any case, it needs to come apart to look before anything else gets damaged..

converter came loose

it is a self adjusting hydraulic clutch, if the clutch is engaging high on the pedal the clutch is worn out.

P0440 - Evap system large leak. This code has a real common problem of the fuel fill cap either loose or the seal or check valve bad in the cap. There are also some hose and lines from the fuel tank to the charcoal canister that can be the problem. But most common is fuel cap loose or bad.

P0495 - Cooling fan rpm too high. This code sets when the control module has commanded the cooling fan rpm to zero and the rpm exceeds a predetermined amount. Your vehicle has a clutch driven cooling fan that the control module regulates through a solenoid valve. Most common problem is a stuck fan clutch which is consistant with the "jet plane" noise you are hearing. The clutch staying engaged when it should be slipping or "idling"
Good luck

usually two types of clutches available,one engages with heat,the other is rpm controlled. The thermal clutch will stay quiet until the engine temp gets too high. Centrifical clutches seem to make more fan noise.
