Hello Zdrivers, I am new to the Z club and need some advice. I swapped a 4 speed with a 5 speed ( L3) The new tranny matched up and everything seems to work well except the speedo. I swapped out the speedomter gear pinion from the 4 speed. The speedometer is not working and was wondering if any could give me some advice Thanks

 

Try installing the 5 speed pinion back in?
