Hello-
Hello, can anyone tell me the length of a tiptronic that shat showed a picture of? Also are they a strong transmission. What are there prices?
You e-mailed me about this when I was out of town, and I replied yesterday, but the e-mail bounced back :-(. Anyway, here's what I said:
I don't know its size offhand. However, remember that it was produced during the era of the G50... so very likely it is of similar length (i.e. longer than 915).
And, it is SIGNIFICANTLY wider. If this is a Type 1 car we are talking about, you may as well remove your frame horns altogether. I think that by the time you are done clearancing, they will be useless. On the right-hand side, you have the longitudinal output shaft and the diff. On the left-hand side, you have a big, wide ATF sump.
But, even at that, size isn't going to be the major hurdle to your conversion. The Tiptronic is a modern, sophisticated transmission. Gear selection is handled electronically - part of the engine computer decides when to shift. This is in place of the traditional valve body and whatnot. So, to make the transmission work, you're going to have to make a computer. Or, you can buy an aftermarket tranny computer for a couple thousand dollars.
I suppose that if you wanted, you could very likely make the thing
manually-shifting without too much research. I *believe* that there are basically electronic solenoids on the tranny that control the hydraulics to shift gears, so if you can manipulate these, you can probably do gear selection. Of course, you still have to build a blackbox computer, only it'll be far simpler, and you still have to create a shifting mechanism. I'm not positive of what I just said, but pretty sure.
I don't know how familiar you are with electronics fabrication, but if not, then I'd steer away from the Tiptronic. Sorry...
Take care,
Shad Laws
