Hey im on vaca in TN and when im in 5th or 6th gear and I hit the gas the car kind of stumbles or jumps. When i take of from 1-3 it doesn't have have a problem. I can hear something slipping right were there Center console is when I floor it from 5th or 6th. i think it's the clutch slipping. I hope it's just the clutch. The car idles fine so im thinking its the clutch. How long will the clutch last(miles wise) thanks. Any experience with the clutch will help.

 

I dont think you have a clutch issue.....

 

any ideas what it could be?

 

How fast are you going when you try to accelerate in 5th, 6th?

If the RPMs climb and the MPH doesn't that's clutch slippage.

Stumbling under load in 5th or 6th could also indicate bad plugs or wires. I'd suggest reading your codes to see if it indicates an engine miss.

 

When I accelerate from 1-3 I go maybe half throttle and It doesn't slip. I don't want to go full throttle in chances of hurting the clutch or anything anymore so I don't know if it would do it in those gears. but when Im in 5th or 6th I was going 60-70 and the car would kind of studder and I hear a squeeking sound right under the radio.

I just seafoamed the motor and changed the oil. Maybe it could be a bad plug or wire. I'm at a cabin right now at pigeon forge/seveirville area. I don't really have any tools to check. Hopefully I don't get stuck here in the hill lol.

Does anyone know any vette shops close to this area?

 

No tools needed to run the codes.

Reading Engine Diagnostic Codes

The Diagnostic Display Mode is entered with the following procedure:
1) Turn on the ignition but don't start the engine.
2) Press the RESET button to turn off any warning messages. (i.e. door or trunk open etc)
3) Press and hold OPTIONS
4) While holding OPTIONS, press FUEL four times within a 10-second period.

Initially, on-board diagnostics go into an Automatic Mode which shows diagnostic codes in a pre-set sequence: PCM - TCS - RTD - BCM - IPC - RADIO - HVAC - LDCM - RDCM - SCM - RFA. All codes will be displayed for each. ( i.e. PCM = 4 codes)

If none are present in a given module, you will see No More Codes on the display.

There are two kinds of diagnostic codes, Current and History designated with a letter suffix, C or ;H.

A current code indicates a malfunction is present in the module displaying data.

A history code indicates a problem existed sometime in the last 40 or 50 ignition cycles. When not accompanied by a current code of the same number, it's potential evidence of a previous problem, now resolved, that was not removed by clearing the codes. More likely it's an indication of an intermittent malfunction.

Intermittent codes are the most challenging of the diagnostics. An intermittent code may have happened once, may have happened more than once but is inconsistent or may be happening on a regular basis but not at the time the codes are displayed. History codes can also be caused by a current malfunction in a system that is not operating at the time codes are displayed. An example is the rear window defogger which doesn't operate until the Body Control Module detects engine rpm. For history codes set by a module that does not operate with the key on and engine off, a special diagnostic tool called a Scan Tester is necessary to properly diagnose the malfunction.

Once the system has displayed all modules, it goes into the manual mode which allows selection of each module using combinations of Driver Information Center buttons. Manual mode can also be entered during the automatic sequence by pressing any button except E/M.

Once the display shows Manual Diagnostics, select a module by pressing the OPTIONS button to go forward or the TRIP button to go back. Once a module is selected, a code is displayed, and if more than one are present;
press GAGES to go forward or FUEL to go back.

To exit the diagnostic mode at any time, press E/M. If you want to erase codes in a given module, press RESET

To reset the codes once in manual mode, press and hold RESET until it displays NO CODES Press OPTIONS to go to the next module. Repeat the steps until you have reset the codes in all the computer modules.

NOTE!! Only reset the codes IF you want to - it is NOT necessary to do this. Clearing a code does not repair a problem. You are simply erasing the evidence of it in the module's memory. If you clear the code/s, and extinguish the Check Engine Light, your emissions status ready will NOT allow you to pass an emissions test until you have completed the required driving cycles.

Once you have the codes, the next question is: What to do with the information?
First, consult the factory service manual. Any serious C5 Do-It-Yourself owner should invest in the Corvette Service Manual of the appropriate model year. The Service Manual is really a requirement if you want to understand and work on your C5.

 

Thanks, I know how to check codes. I don't have any except one for my 02 sensors. The car idles fine and I can rev it to like 5 grand and no stumbling or anything. I just hope I make it home then can really find out wihats going on.

 

Clutch slippage in 5th or 6th gear is a classic clutch problem, when engine revs and speed does not "keep up" with it. Because of the load, a failing clutch will slip in the higher gears first. Depending on the amount of clutch slipping, you may also smell the clutch (smells hot).

 

No codes most likely means it's not a plug or wire problem or it should throw a P0300 Engine Misfire Detected.
