Doctuh-

Slave cylinder is INside the bellhousing/tranny.. So tranny removal is a must..

note: slave shares the fluid with the brake master cylinder. So after a few years a good flush & refill is very beneficial to both systems.

Course that applies for any vehicles using hygroscopic Dot-3 or even Dot-4..

Too bad we can't use silicone based Dot-5, like certain Harleys do..

Or you could use the NLS feature thats on yours.

Silicone fluid(DOT5) is not exactly the best choice either....especially a vehicle exposed to moisture (master cyl exposed IE-bikes). Good for racing where frequent maintenance is performed..not so good on vehicles where it isnt...bikes are bad too because of infrequent use. Silicone has a softer feel and requires yearly change. DOT 5.1 is a better bet because of its glycol base, longevity , and resistance to moisture separation. DOT5 not recommended for ABS as the moisture is not absorbed and collects on any metal parts causing corrosion.

Pull forward 1/2 car at a time or someone jumps the spot.
Average under 5 MPH on "America's Technology Highway" for miles
F**k all that

I do many 500+ mile trips and some 1000+ in 1 day so the auto was a good choice for me
I have a bum left ankle so it was also an easy choice.

I've had many cars with either trans

The HHR's trans has never given me any trouble and seems appropriately strong enough for the stage kit

You like shifting - power to you, you don't like it get the auto and enjoy

I disagree & can post links also..

Dot 5 will change color when ready to be changed.. & Of course it's not for ABS bikes or autos..

I use Dot 5 in my bikes & doesn't require changing till over 4 years...

DOT 5 is good for show cars where its stored and have low mantenance..also does not attack paint which is a sore spot for classics. Harley stopped using 5 starting in 05 and all bikes by 07. MOST racing types stay away from it, since moisture is NOT absorbed it lays in low areas and turns to steam on hard braking ( steam = air) thus a spongy brake. It requires scheduled changes and cannot be mixed with other fluids. Unles the sytem was designed for it I wouldnt use it. Not recommended for daily drivers where brake maintenance isnt addressed regularly,like 2 year flush cycles. The pluses do not exceed the negitives..being the only high point is higher temp boiling points, of which if your not racing, its not worth the problems. The only safe way to flush is pressure bleeding,otherwise moisture and air will be introduced and performance degraded. DOT 4 is best all around and DOT 5.1 offers a bit more heat tolerance and helps problematic brake systems........Even the military is weaning off silicone. But like spark plugs, oil types and chg intervals, its all up to the owner, believe what you want, the facts are out there.

Yes because then started adding ABS to the bikes. Started with the baggers. And so not to confuse their techs, they switched all back to Dot-3 hygoscopic crap.

edit: I have been using Dot-5 in my Flathead (juice brakes) for about 20 years.
