Why does my 93 N* Transmission Shift very Hard when Hot? There are No error Codes...Just History Codes But, The Check engine Light comes on. What could be the problem?....BTW, I found out how to look at the PCM, ACP, TCS and so on Paremeters, But what do they stand for?:yup: :yup: Some of the Paremeter are High ANd Some Are Low.

It sounds like the Input Speed Sensor, that is in the transmission. Does the P056 code set? This will cause the problem you describe.
