Loss of power if 5th/6th gear

BigDog · 12-21-2009, 01:31 AM

I've been noticing that I have a loss of power when I'm in 5th or 6th gear lately... car takes off just fine and accelerates without issues from a standstill... but as I get higher in the gears, it seems to rev to say 3500... then drop to 3000... and then slowly move from there...

no strange noise or smells either...

any ideas?

NiVeDh · 12-21-2009, 01:41 AM

6MT or Steptronic?

BigDog · 12-21-2009, 01:44 AM

6MT

NoSurrender · 12-21-2009, 01:45 AM

hmm... 5th and 6th gear. Did you happen to hit somewhere around 130-135mph?
If so, that'd be known as your limiter.

BigDog · 12-21-2009, 01:46 AM

no not at all... like 65-80mph

NiVeDh · 12-21-2009, 02:10 AM

How many miles on the car? Could be clutch problem?

ProjectD865 · 12-21-2009, 02:11 AM

Perhaps your clutch is slipping?

Jlomb436 · 12-21-2009, 02:25 AM

I can only imagine that in 6th gear at 3500 that your approaching the limiter quickly?

No way.

62000 miles on the car

Powertrain problem. Take it to a mechanic and have it fixed. Have a credit card or large checking account balance ready, you'll need it.

best of luck...

Loss of Power? Kind of broad?

REv to 3500 then drop 3000? While on the gas? Slipping clutch?

BigDog · 12-21-2009, 11:37 AM

looks like the clutch is slipping... happens now in all the gears as of this morning... dropped it off at the mechanic over in westfield, nj

Hi,

Something's not adding up. When a clutch starts to slip, the engine RPM's go up, not down. An easy test is to stomp on the gas in a high gear and see if the tach shows an increase in RPM even though the road speed stays unchanged.

Let us know what the mechanic uncovers, please.

Regards,
Adnan

The HACK · 12-21-2009, 12:49 PM

Any warning lights on dash?

I would have to agree, that if it's slipping clutch then the RPM would shoot up, not gradually drop down.

Jeff@TopGearSolutions · 12-21-2009, 12:51 PM

You can have a slipping clutch and have the RPM go up then back down.

All it means is the clutch slipped then it caught and dropped back down.

Ah, got it. I misunderstood the OP's post slightly.

Thanks,

2nd, that is all that is happening. Clutch will take longer and longer to grab as it wears out and eventually wont grab at all.

thats exactly whats happening, i miscommunicated... the RPMS do go up.... but I don't get power engaged until a few seconds later, and by then the RPMS have gone down a bit
