Transmission Fluid Change
I've got a 2000 FRC. I read on the FAQ that is posted that the 98-00 used a paper filter that is incompatible with synthetic ATF fluids. I wanted to change to amzoil or mobil 1 ATF synthetic fluid, it's getting aruond that time with almost 60K on the car. Help is appreciated

The problem is with paper blocker rings from what I remember, and has something to do with the base certain synthetic oils are formulated from. I believe Amsoil isn't a problem. I think Redline was ok, but I would definately wait for confirmation from someone who definitely knows.

I researched this a couple of months ago and can't remember the exact response but I know it did not include 99 and new vettes. I went with synthetic Mobile 1 and it works great. Smoother shifting to you. I assure you I would not have put it in my car without having the forum o.k.

You caan now purchase Dexron VI, available thru dealers now and rasonably priced. It is the new standard for GM transmissions. I've had Red-Line and Mobil 1. Just switched to GM Dexron VI and it is the best yet I have tried. Can be retro-fitted to all transmissions.

One of these comes in handy for DIY:

While you are under the car changing the ATF, might as well change the differential fluid as well...I use Mobil 1 there too.

I stuck with conventional Valvoline Dexron III ATF and it alone improved the shifting quality. Previous owner told me he had put in Redline before; not positive, but the shifter was definitely very notchy. It's a lot smoother now; not quite as nice as the German/Japanese gearboxes though.
Note: On my '00 FRC, the fill plug on the driver side did not have a temp sensor attached to it. The temp sensor was higher up on the passenger side; the fill plug was a simple plug like the drain plug. Took about 3.5 qts before spilling out.
