Default Bleed the Clutch and Change Tranny Fluid

Having some shifting issues in the ol LS1. Would like to bleed the clutch and replace the transmission fluid. Any advice?

Never bled a clutch before. Best way to do so?

Best type of fluids to use?

Unless you have the speed bleeder installed you're going to have a tough time bleeding the clutch. Transmission fluid is a little easier, I use Pennzoil Synchromesh. Drain from the bottom, fill through the shifter. 4 qts.

Is there no other process to bleed the clutch?

The text book process is a two person process with one person underneath the car with a wrench on the slave cylinder bleeder screw.

If you haven't replaced that bleeder screw with a remote bleeder and want to avoid this the textbook method, you can find some youtube videos of a MightyVac method but it may not give you a perfect bleed.

If your clutch fluid issue is just old and dirty fluid google the Ranger method with a syringe to feed and bleed it (Corvette blog). Clean fluid is essential. Takes about 15-30 minutes. Then you can decide if there is air in there as well. I've never bled the clutch, just Rangered it twice per year.

There's a current thread running on trans fluid which covers every possible aspect for your choice of fluid.

Umm, are you referring draining the transmission fluid and filling from the shifter? The reason I am asking is when I changed my transmission fluid in my M6, I drained from the bottom of the transmission and filled through the upper bolt on the transmission?

Did I do something wrong?

Thanks

There are two ways. 1 is from the top through the shifter and the other is through the top (most likely where you did) with a pump attached to your bottle, or using a funnel of some sort.
