hi jack,

i would put the r&r of this pressure valve in the realms of the good diy
home mechanic with the right tools.

not having done it myself you understand: but the valve body looks easy to
get at, and the pressure valves screw into this...

hth,

My 98 A8 entered limp-home mode once before, but without a code when I later
checked it.  It did it again recently, and I checked the codes prior to
shutting off the car.  It threw the following tranny code:
18242 - Pressure Control Valve 5 (N233): Open or short to ground P1834 -
35 - 00 - -

In both cases it happened while stuck in traffic for a while, and finally
starting to go again.  Engine revved strangely high (like no clutch
engagement) and then some rock-hard, abrupt shifts, one of which eventually
throws it into limp mode.

Fluid completely changed 12K miles ago.  Fluid still full and clean.

Anyone have experience with this, or know what the pressure control valve
is?

Thanks,
Jack Rich
