I am changing the tranny filter, and need to know the torque sequence, and torque spec on the bolts. Can anyone help me out here??

 

I don't think will answer all of your question, but might be helpful...

From the SM:

>>Inspect the oil pan bolts and washers to determine if the conical washers are reversed.

>>Reuse the oil pan bolts and washers if the conical washers are NOT reversed (1).
Replace the oil pan bolts and washers if the conical washers are reversed (2).

>>Install the new oil pan gasket to the oil pan sealing surface.
Position the oil pan to the transmission case and support the oil pan.

>>Install the oil pan bolts. Tighten the transmission oil pan bolts alternately and evenly to 11 N·m (97 lb in).

>>Remove the transmission fluid check/fill plug.
Fill the transmission with DEXRON®-III automatic transmission fluid through the check/fill plug hole until fluid begins to pour out, then install the check/fill plug hand-tight.
Complete filling the transmission with fluid to the proper level. Refer to Transmission Fluid Checking Procedure .

>>Tighten the transmission fluid check/fill plug. Tighten the transmission fluid check/fill plug to 30 N·m (22 lb ft)

>>Inspect the oil pan gasket for leaks.

 

Thanks guys!

 

This is saying the same as Patches. I used this procedure to change mine.

Changing ATF in a C5 is no more difficult that it's been in Corvettes of the past. Support the car safely, place a drain pan under the transmission and remove the fill plug. With the engine not running, the trans pump is not circulating fluid so there will be significant drainage out the fill plug hole. Once that stops, support the trans pan and remove its bolts. Carefully remove the pan and drain the remaining ATF. You may need to tap the pan with a soft hammer to break it loose.

Once the pan is off, carefully inspect its bottom. There may be a silver or gray residue there. A tiny bit of residue is normal, however, a significant amount means the transmission has a problem. The definition of a "significant amount" is hard to characterize. If you see more than a dime's worth of metal in the bottom of the pan, overhaul it." Be it a dime's worth or a significant amount, if you see that in the trans pan, put it back on, refill the trans and take the car to a transmission service facility for diagnosis and possible repair.

If there is no residue or a just tiny bit, set the pan aside. Note the position of the filter to aid in installing the new unit. Then, remove it by gripping it firmly and pulling down while twisting a bit. Discard both filter and filter seal. If the seal is stuck up in the valve body, pliers will usually pull it out. Remove all traces of the old gasket from the transmission case and pan. If a significant amount of the gasket is stuck to the pan and you have a quarter-inch-chuck, die grinder, a great way to remove it is with the Gasket Removal Kit from Standard Abrasives Motorsports Division. This kit contains abrasive discs that fit on the die grinder and will quickly remove gaskets but not harm the pan. Because of the threat of gasket and abrasive particles getting into the transmission do not use those discs to remove gasket material from the trans case. That you will have to do with a scraper.

Obtain an ACDelco trans filter kit (p/n TF306). Install its new filter seal in the valve body then push the new filter in place. Clean out the trans pan and look closely at its bolt washers. Their flat sides go towards the pan. If they are reversed, get new bolts. If they are not reversed, reuse the bolts. Apply the new gasket to the pan. Install the pan and torque the bolts to 8 ft/lbs.
Add fluid until it leaks out, then install the fill plug. Perform the fluid check procedure described below, add more fluid as needed. Since 1994, the factory-fill fluid in Corvette automatics has been an organic-based ATF meeting the Dexron III specification. A suitable performance upgrade would be a switch to or Red Line Oil's D4 Synthetic ATF or Mobil 1 synthetic fluid.

If you are going to check the trans with the car on stands, make sure it is high enough for you to safely move and work while the exhaust system is at operating temperature. Start the engine and, using the "gauges" button on the driver information center (DIC), put transmission temperature on the IPC display. Run the engine until the trans temp is between 86o and 122oF. Apply the brakes and shift into each gear for a few seconds, then shift back to park.
Set the parking brake, leave the engine running and crawl under the car. Position a drain pan under the fill plug area and remove the plug. If fluid dribbles out or is right at the bottom of the fill hole, your transmission is full. If fluid leaks profusely, it was overfull and you should allow the excess ATF to drain into the pan. If no fluid comes out you will add more.

 

Transmission pan bolts torqued to 8 ft-lbs, or 97 ft-lbs?

 

No.

 

So what is the correct torque?

 

97 lb inches or 11 Newton metres according to the service manual.

 

Got it. Thanks for the help.
