Under the hood

What is your question?

So we recently put in a new tranny in a 95 golf amd the tranny came from a 93 jetta so we had to buy a clutch kit so the splines Matched... Now we dont have reverse amd the shifter feels like it doesnt want to stay in place.. Is it the linkage or something wrong with the clutch cable or the clutch itself or possibly the tranny??? I have a 2.0L engine with a 1.8L tranny amd clutch installed.. Does that matter?
