does anyone know how to or have a link to find out how to check trans fluid on 05 vette with auto thx

 

2005 owner's manual, page 5-21.

 

I have 2005 C-6 A-4 Trans also.
Look in your manual and it will say there is no need to check unless there is a leak.
Though lately I have been thinking about changing over to Amsoil synthetic tranny fluid for this transmission I'm close to 30,000 miles.

 

mine has 70000 miles it has a little drip and i want to check the fluid till i can fix it

 

Time to drop the pan

 

Here are the basics of checking the transmission fluid in an A4.


Start the engine and allow the engine to idle until the transmission fluid temperature has reached the value specified. (86 - 122 deg. F)

Depress the brake pedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to the PARK range.

Raise the vehicle on a hoist. The vehicle must be level with the engine running and the shift lever in the PARK range. Refer to Lifting and Jacking the Vehicle in General Information.

Caution

The engine must be running when the transmission fluid fill plug is removed, or excessive fluid loss will occur. Transmission fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any lost fluid. Do not turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the oil fill opening.

Remove the transmission plug.

Important

The transmission fluid may darken with normal use and does not always indicate contamination or oxidation.

Check the fluid color. If necessary, use a small screwdriver as a dipstick.

Is the fluid color clear red or light brown with no burnt odor?

Does the fluid have a cloudy or milky appearance?

Check the fluid level. The fluid level should be even with the bottom of the threaded plug hole.

Is the fluid level low?

Add DEXRON III automatic transmission fluid in increments of 0.5 L until the fluid drains from the plug hole.

If you add more than 1.5 L to the transmission the transmission may have a leak. Refer to Fluid Leak Diagnosis .

Was a transmission fluid leak found?

 

Good information.

 

thanks for all the great info

 

Let us know what the diagnosis is and what kind of trans fluid you put in like Amsoil or Dex 6.

 

LS WON,
AMSOIL recently increased the viscosity of its AMSOIL ATF and it is no longer recommended for Dexron VI applications. As that leaves them with a void in their product line, it wouldn't surprise me to see a new offering to fill this void. If I hear anything, I'll let you know.

 

Thanks please keep me posted there are tons of products out there and it can get confusing. I think it is safe to put in the Amsoil Severe Service 75W/90 synthetic rear end oil with 1 bottle of friction modifier.
(Does chevy currently use synthetic 75W/90 hypoid gear oil or synthetic gear oil?) For the transmission then if done now it would then be the Dexron 6 which I do believe is synthetic unlike the original Dexron III that was recommended on the 2005 A-4 and wasn't a synthetic auto trans fluid. Correct me if I'm wrong on this one as Chev. came out now with the Dex6.

 

The gear oil is 75w90. Amsoil is good as is redline. Im even using valvoline in mine as that is what rpm recommended I put in for the diff swap. I have castrol tranny fluid in mine now as it does have the gm spec. If in doubt just get some tranny fluid from the dealer.


The lenghty procedure above is the correct way to service your tranny. It is long and a PIA but that is the only way to make sure it is not over or under serviced. DO IT RIGHT or pay the price.

 

So Chev. does use regular petrol 75w90 gear oil.
I'll switch over to the synthetic brand. Maybe Redline since it is easy to find.
On another car I have I'm using the Redline products in the rear diff., manual trans, and power steering. I can feel a big difference with the manual when I shift.
As far as the rear diff redline fluid goes you don't have to add any additional friction modifier to it and Redline doesn't offer you the option to add more friction modifier like Amsoil does.
Redline is alot easier to find than Amsoil.
The Auto transmission service is something I will let the dealer perform and I know there are 2 ways one is just drain and change with screen and the other is a power flush. I think there is alot of tranny fluid in there so it will get messy and I will let dealer do that maintenance.

 

The correct diff lube is now Dexron LS Gear Oil 75W-90 which already has the friction modifier in it. I just changed mine out 2 weeks ago and the rear-end has never felt better!

 

no gm uses full sythetic from factory with built in friction modifier

 

I believe the procedure is the same for the A6 tranny, but the fluid is now Dextron VI.
Someone told me Dextron VI is also approved for the A4 but I have not tried to verify that.

 

the Dexron 6 is synthetic fluid and the Dexron 3 used in 2005 is regular ATF fluid

 

I have not read anywhere that GM has come out and stated emphatically that Dexron VI is synthetic. Most believe that it is a synthetic or synthetic blend. Likely a Group III fluid.

As for your question above, the Corvette diff is factory filled with synthetic 75w90. The current fluid is listed above. Would still go with the Group IV basestock AMSOIL Severe Gear Extreme Pressure Synthetic 75w90 (product code SVGQT) and one bottle of AMSOIL Slip-Lock Differential Additive (product code ADABA).

 

Amsoil then is coming out with a Dexron 6 Fully synthetic auto trans fluid for the 2005 A4 Corvette which initially used Dexron III?

 

Correct, the A4 factory fill was Dexron III. The A6 transmission currently uses Dexron 6. If you are switching over to a fully synthetic you would want to have a complete flush and fill done.
