This is my last resort I bought an s1 sequential shifter 4 years ago for my T56 tremec in my e30m3 I have covered 1700 miles in this time with the shifter and had nothing but problems which some have been sorted, anyway last few times I have gone out in the car the shifter has stuck between 2 gears and won't move I contacted s1 after weeks they finally replied and told me to take it apart to see if there was any damage, this I did i sent s1 all the pictures of every part 3 weeks later they got back to me saying they couldn't see any damage to any parts. So I've asked them for distractions to put it back together or a video this they have refused to do so where do I go from here???

 

I doubt many people use the S1 sequential shifter so probably not going to get any answers.

 

Maybe some Rally or road race forums, they are illegal in almost all road race classes except GT/SP/EP though..
Most guys that were serious about a sequential just bought a sequential.

I saw these in a few endurance cars , mustangs, camaros.

 

Hate to sound like a dick, but sequential shifters in car transmissions are for people chasing a few hundredths or even thousandths of a second in pro racing. Sequential shifter "lookalikes" for regular transmissions are just useless pieces of **** that accomplish nothing of value. If a sequential shifter can even give you a few tenths of a second better time, you suck at shifting.

 

Does box shift ok with a normal shifter in place ? Does S1 shifter operate free when used not bolted to the box ?

 

THe sequentioal conversions are really hard on synchro's as well, you really need a dog box to take advantage.
