Install: Pro Lex GII Short Shift Kit

The Pro Lex GII Short Shift Kit installs on all 2002+ IS300 5 speed models. This kit reduces the throw gap between shifts, allowing for more precise and faster shifting. Not to mention a very racy feel while driving. The shift stalk is also significantly lower than the stock lever.

Notice from Pro Lex Performance: Do not downshift if you are going faster than the maximum allowable speed for the next lower gear. To get on a highway or to pass slower traffic, maximum acceleration may be necessary. Make sure to observe the following maximum allowable speeds in each gear. 1st: 35 mph; 2nd: 60 mph; 3rd: 91 mph.

I was reading some posts... some .netter's
tranny failed at 4k due to Pro Lex Performance Short shifter. What generation was it? Was it because of mainshaft overplay? (It doesn't have the gate so you can keep going....)

<P>Is this problem only for the first gen? Is it faulty due to self installation? (I've seen other people have it on for the longest time without any problem.)

<P>I have a B&M shifter now, but I drove a friend's PLP gen-2 shifter... I liked it a lot. Is there anything I should worry about with the B&M?
