Dana,

VW made the switch to the radiused key grooves right around 1990, so
your
trans may or may not have the improved version.

I wouldn't worry about your R&P unless the trans starts making strange
noises. You are, however, getting close to the mileage where these
transmissions need to be rebuilt.

Rebuild price for your trans is $1025 exchange.

Regards,

Chris Weddle
