The Internet can be a cruel mistress. Years can be wasted dredging through decades old forum posts trying to find the most obscure information imaginable. Other times, you pop onto eBay, find a part that says it fits "GMs and VWs", shrug, say "well, it's $21 to find out, innit?".
I mean, the Porker trans is essentially a VW box with another gear stuffed in it, right? Right!
This little guy helps Chevy guys run older transmissions in more modern vehicles that would typically have electronic gauges. It's essentially a retrofit vss. It also happens to have the same threadpitch and diameter as a Porsche 901 speedometer drive.
So, one GM 16k pulse per mile VSS and one Porsche speedometer drive unit.
The issue is driving one with the other. Both have a male drive portion, so a little berkeleyery is required. The VSS has a square drive that fits snuggly into a .125" hole.
The Porsche half of the equation after some trimming and very, very careful drilling. Have you ever drilled a .125" hole 1" deep into a part you probably can't afford to replace? With a hand drill? No wonder I never make any progress on these stupid projects.
No joke, I have close to an hour of my life invested in that little hole. rimshot
Obviously, I would love to have broached that hole, but obviously that's a bit beyond the scope of a guy in his shed. Luckily adhesives have really come a long way in recent years.
I have some production equipment held together with this stuff at work, and it is absolutely incredible. Without saying too much, millions of miles of product has relied on this adhesive in a similar arrangement and it has yet to fail. Hopefully this will be much the same story.
I gave the trans "The Full Arthur Fonzarelli", and am quite happy with the outcome. It might get the JTHW8 treatment at some point, but it's going to be hard to go back, now that I've gone black...
Tune in next week for more double entendres. Maybe even some Fiat progress?
