Sorry if something like this thread already exists. I've seen a couple mentions to doing this, but nothing all that detailed. Grab a beer because this post is a bit long...
Basically what I wanted to do was replace the factory sloppy 02A shift box/cable setup, with something more precise and newer feeling. On all of the 02J/02M cars I have driven, the shifters felt much nicer and more solid/precise than my 02A setups.
My reasons for performing this swap are:
-More precise shift feel
-Much less 'slop' than the factory 02A stuff
-Readily available short shift setups (TT shifter, B&M, Diesel Geek etc).
-Readily available parts (from any 02J car).
First off the parts required....
-Your original 02A transmission is retained so that is a plus
-02J shift box and cables (with cable bracket that mounts to the tranny)
-02J shift tower/shift weight
-02J shift tower receiver portion (this was required on a G60 box, but not on a VR6 box...the part I am talking about is on the bottom of the tranny and sometimes has the VW logo cast into it...it accepts the shift tower shaft on the transmission).
-02J style shift knob, aftermarket knob which attaches via set screws, or some way to thread the 02J shifter shaft to 12x1.5mm. The 02J shifter shaft is not threaded like the Corrado/other VWs. It is also slightly larger than a 12x1.5mm die, so threading it may be quite hard. I gave up and am just going to run an aftermarket shift knob with set screws.
-(2) 8mmx1.25 bolts, 50mm in length
-(30) or so 5/16" washers
- New style reverse light plug/connector
Note: There are 3 styles of shift towers/cables. The very early style uses a shift tower with plastic connection points and a big black plastic housing on top of the shift tower like the 02A VR6 shift tower. It also uses a shift box/cable setup very much like the 02A stuff. I would not recommend using this type of shift tower/cable/box setup. The 2000+ styles use all metal on the shift tower and connection points, and a floating ball design at the shift box (the piece you shift with pivots on a ball). The 2 recommended types are described here...The early style (2000 to 2002 I believe) uses ball/socket style cable connections at the tower. These are at the up/down and side-to-side connection points on the shift tower. If you run this style, you must run the cable ends that match. The late style is 2002+ I believe, and uses a pin and retaining clip. If you run this style shift tower you must use this style cable ends. The cable ends are interchangeable though, so if you have a ball/socket shift tower, and a pin/clip style cable setup, you can just source ball/socket style cable ends. I am using the later pin/clip style.
The top box is a stock 02A shifter and the bottom is an 02J. The 02J uses a floating ball design and feels much more precise than the older 02A box.
Box/Cable assembly comparison. In the pic the 02J box starts a bit to the left when compared to the 02A. Also on the 02J box, I do not have the cable ends attached, but overall cable length is very similar when lined up side by side.
And here is the 02J Shift tower assembly (mounted on the 02A..I'll detail this later, but wanted to show what it looks like so you can compare to your factory 02A.
I'm adding more details/pics/instructions in the next post to keep this somewhat organized....gimme a few mins....
