On a manual transmission will the clutch slip if there is not enough oil in it? Or at least act like its slipping? Answered

I have a 1999 Nissan Maxima with a manual transmission and has 120,000 miles. Within the past few weeks, I have noticed that I am able to get into all gears while driving but when I step on the gas the rpms go higher than normal- then come back down. Just wondering if this could be a symptom of not enough gear oil in the transmission?


could be worn out like they said less somethings ina bind on you engage disingage> hardware <somewhere and that wouldnt be normal! so ...
   for the benefirt of the subject in general outher makes it would be that you need to adjust your clutch linkage cable or rod imediately also be mindful
    of your clucth thickness when you install or change clutches

To add: If your clutch has been recently-replaced, have the clutch-release adjustment checked and re-calibrated. If it has been some time, replace the clutch immediately as it is either worn or damaged, and will cause more expensive damage if used further. Be sure that the mechanic checks for evidence of "rear engine oil seal" leakage AND "input-shaft seal leakage" as a precaution. ANY, EVEN SLIGHT, CONTAMINATION OF OIL ON THE CLUTCH FRICTION-DISC RUINS THE CLUTCH ASSEMBLY. Any reputable shop will require employees to wash their hands prior to handling any clutch component whether new or existing. If you have not replaced your clutch recently, it may be so worn that it can get worn-down to the rivets, which if they make contact with the flywheel, will require that it be resurfaced, which adds a few hundred dollars more to the cost of the service. Be sure to have the entire "clutch release mechanism" inspected as well. 75% of the time, your problems are simply a worn-out clutch. 10% are due to oil-seal leakage from the engine or transmission, 13% are due to improper clutch-release adjustments, and 2% are due to clutch-release mechanism failures.

As a racing and lifetime professional in the industry, your clutch is worn-out or contaminated, either requiring a replacement and possibly a check of your engine's rear oil seal. If your foot is completely off the pedal and it slips for ANY reason, you need a new clutch....the reasons why are found upon the replacement procedure. There is NO other option with exception to an improper clutch-cable adjustment. There should be just a little tiny bit of "wiggle", or "play" in the clutch pedal. If there is, the clutch is gone, only replacement will discover why. If not, adjustment will correct the problem, but the excessive wear has already been done, because that clutch is slipping even when you don't feel it. At the least, you will need a flywheel resurfacing and a completely-new clutch kit.

Your clutch is unfortunately worn out... As moe has said, there is no oil anywhere near the clutch, the clutch is inside the bell housing between the motor and the transmission. The oil is inside the transmission itself. Lack of oil would make changing gears hard and damage the transmissions input and output bearings, but would not cause the problem you are describing in a manual transmission.

yeah sounds like not enough pressure for your clutch or your clutch friction disc is worn out. Nothing like the smell of a burning clutch! yummmmm

In a manual transmission, gear oil (or grease) should not come in contact with the clutch at all. The idea is that when you release the clutch pedal, very high tension springs hold the clutch plate to the rotating disc connected to the engine. The material on the clutch plate is similar to the brake pads, and friction is necessary to transfer the rotating energy through the transmission to the drive system and, eventually, the wheels. Oil or grease would just make it slide, and your car would not move very much at all. It sounds like the clutch either needs adjusting (i.e.- more pressure on the plate) or complete replacement.
