I have been driving manuals since I was 7 years old. I am 30 now. Every time I try to double clutch quick I get angry noises haha. I have never been able to master it and I am on my 7th manual!
Your trying to tell me new road ranger trannys have syncros? I know every one Ive taken apart has sliding clutches, deff no syncros.I have rebuilt many 6 - 18 speed transmissions single double and triple countershafts. All had synchronizers except really old ones so why wouldnt it be beneficial?
