I'm currently saving up for a BTS. I got to thinkin and thought i would post on here to get you guys opinion.
how hard would it be to convert my current auto to a 6spd?
A real PITA, you pretty much would need a donor truck with a tranny, transfer case, drive shafts (maybe), bell housing, clutch, clutch fork & mechanism, clutch pedal & master cyl, PCM and a vehicle harness for a manual tranny truck. All that and likely more as well as a taller floor pan in the cab tranny tunnel. (The manual tranny is taller and req's a bigger hump.)
What are the advantages/disadvantages of both?
I've already indicated the disadvantage of converting to a manual.
I've never heard of anybody with a legitimate complaint against a BTS, except maybe the price. But in this case, it's a matter of you get what you pay for. I've had one for around 6 or 7 years now. It hasn't as much as even hick-upped in around 130,000 miles.
