Tremec TR6060 Fill Level (6g Camaro)

[thescreensavers]

In my 6th Gen Camaro service manual it states

Quote
"IMPORTANT:
Transmission fluid level setting must be followed exactly as written or the
transmission may be overfilled or under filled. For fluid recommendations, Refer to Adhesives, Fluids, Lubricants, and Sealers (MM6)

Transmission fluid level MUST be 3.2 mm (1/8 inch) below (1) the fill plug. This can be done by one of the following methods:

1. Bend mechanics wire to 3.2 mm (1/8 inch) to check fluid level. Add or remove fluid as necessary.
2. Fill transmission until level with the bottom of the fill plug hole, then remove 240 ml (8 ounces) of fluid."



Its very interesting that they ask to remove some fluid, this also assumes the car is level.
What is also interesting is that on all other cars with the TRE6060 removing 8oz of fluid is not mentioned anywhere.


So the question is how important do you think it is to remove 8oz of fluid? It would seem Tremec designed the fluid level and GM for what ever reason modified it.

What happens if it's overfilled? Does it have a vent to blow it out of? Hard to believe that 8 oz would hurt anything.

Perhaps accounts for some of the high G forces on the fluid it could see in the Camaro application, which could slosh it around to areas that may be detrimental to transmission performance.

Don't need to remove the 8 oz 'surplus' fluid, leave it within the trans, for additional 'margin of safety'.
Depending on the bearing dimensions of the smaller size of the two input/output shaft bearings, OEM 'designed' fluid level in a transmission is typically 1 inch below the centre lines of input/output shafts and all components within are concentric and none of them is 'off-centre/ eccentric' , unlike crankshaft component in an ICE engine.
