They're not necessary but make life much easier. Remove that circlip with some snapring pliers. make sure you don't let the transmission free hang if it comes off your jack bring the jack up until it is holding the weight. remove the 4 bolts to the transmission crossmember place a jack under the tranny crossmember remove the 2 frontmost bolts holding up the heatshield and let it hang. Next, remove the exhaust heat shield (the real reason you have to remove the exhaust, as it blocks all access to the relevant area): lower the exhaust and set it on some blocks to keep it from hanging. careful on the aftmost one as it is holding your exhaust up. remove the center bolt of the exhaust hanger attached to the tranny housing. as a reminder, WD40 is not a true "penetrating" oil like PB or liquid wrench.) a little PB blaster or your favorite penetrating oil ahead of time will help things out. separate the 4 bolts at the bottom of the headers (these are $22 inconel bolts with pure copper nuts so be careful. i'm not responsible for you doing this wrong.)įirst things first, you have to lower the exhaust: (as always, undertake these projects at your own risk. Quick rundown on the stuff before I started snapping pics: Dinan's billet short-shifter has a 20% to 25% reduction in throw with a self-lubricating bearing for the ultimate in smooth short shifter technology.This DIY will serve as an 'in the family' addendum to already excellent instructions provided by UUC for installation:īig thumbs up to UUC for their pretty excellent instructions, and a major thank you to m圓30i for detailing everything very well.Īs a baseline, I snapped some shots of the stock ZHP shift lever with stock ZHP knob: The short-shifter is also rubber isolated for a solid feel and vibration-free operation. Other manufacturer's shifters employ metal components that tend to be noisier and induce a notchy feel. In addition, Dinan's short-shifters retain the nylon pivot ball and shifter bushing providing the same smooth and quiet operation as the original shifter. The Dinan short shifters are application-specific as well in order to achieve an appropriate reduction of throw providing the associated benefits without making the desired gear difficult to locate or require inordinate effort, a common complaint with other manufacturers" short-shift kits where a ''one size fits all'' approach is common. Larger BMW models with larger gearboxes require more leverage to make the gear changes which is why BMW employs different shift handle configurations for various applications. Dinan's billet short-shifter kits effectively reduce the amount of throw necessary to make gear changes providing a sportier feel.
