Expert: - 4/27/2011


Question
On the right rear of the trans is a drum that looks like it helps with braking. There is a small pipe sticking out of the bottom of it and it drip's a small amount of fluid. Is there a seal in there, I don't see one in the parts exploded view.

Answer
Hi Brad:
The drum-like device on the right rear is the Brake Accumulator Sphere.
It certainly helps with braking. The Accumulator Sphere should be sealed.
However, at the top of the transmission, there is an overflow valve to
let out transmission fluid in the event the transmission is over-filled.

Make sure your leak isn't coming from that. You can easy tell by the type
of fluid. As you know, transmission fluid is red and brake fluid is clear or
slightly discolored (depending on age).

If the fluid is coming from the transmission overflow valve, you most likely have
too much fluid in the transmission. The is a common problem I see a lot with RR.
You have to drive a RR for 20 to 30 minutes to get the transmission good and hot
before checking the fluid level. Anything less will give you a false reading and
cause you to think you are low on fluid. This leads to overfilling. So make sure
this is not the case first.
