I Replaced My Cluster Yesterday. I Didn't Change The Code Plug, Just Simply Replaced The Whole Assembly. Below Will List Problems Before Switch And After.....

Before:

Fuel And Temp Gauges Did Not Work At All.

Speedo Bounced Around A Bit, But Was Mostly Accurate

Tach Worked Most Of The Time, But Would Spaz Out From Time To Time

Lcd Displayed "coolant Temp" All The Time.

Shift Position Indicator Did Not Work At All Or Light Up.

After:

Fuel And Temp Gauges Work Properly.

Tach Works Properly.

Speedo Still Bounces Around A Bit

Lcd Display No Longer Displays "coolant Temp" And When Button Pressed, Displays "check Control Ok". However, Now It Displays "trans Program" When I Turn Car Off.

Shift Position Indicator Works For Only The First 10 Mins When Starting Car. It Also Displays An "e" In Front Of The Selected Gear. After Running For About 10 Mins, This Display Goes Completely Out.

That Said..........

I Was Worried That My Tranny Might Be In Limp Mode After Getting The Trans Program Displayed. It Is Not. The Tranny Works Perfectly.

Is It Possible That I Need To Unplug The Batter To Reset The Unit? Are The Problems I Am Still Having Due To An External Source Other Than The Cluster? Cant He Speedo Problem Be Related To The Sensor? Where Is The Speed Sensor Mounted?

Thanks......
