I have a 90 park ave with a lot of miles. I was able to pull codes 27 28 and 29. The book I have does not give any information about these codes.

I have a 90 park ave with a lot of miles. I was able to pull codes 27 28 and 29. The book I have does not give any information about these codes.
According to my 91 Service Manual for my Bonnevile Code 27- 28 - 29 is for Gear Switch Diagnosis.
The Gear Switch is located in the transaxle.
