Anyone else keep snapping roll pins?

For those who don't know what they are, they attach the shifter arm to the transmission. I keep snapping them. I just put in my third one today. It's not hard but it is a pain in the ass to get to. I used a tension pin this time so we will see how long this one lasts.

I guess i just shift too hard. I am used to driving my Camaro. It has a t56 six speed.

If anyone else has this issue too post up.

I've only broken them once so far, I had a shop fix it because I didn't know what was wrong. I try not to shift as hard now, but it's tough to resist.

I've had the B&M for quite a while now. even when I do bang through gear (like sunday) she's still fine. I may just take things apart when I do the new turbo to see the condition of it

Not that I can being critical of eveyones problem...but how the hell are people breaking roll pins all the time - and bending bolts! ****...you guys must really slam the hell out of your shifters. The pins are probably breaking in order to protect you from screwing up your transmission. Your syncro rings need time to speed match the gear that you will be currently selecting so that the "dogs" on the selection ring can engage to gear on the driven shaft - the driven gear needs to be at the same speed as the selection ring. All this speed matching happens during your shifter movement in between gear selection. Your roll pins are there to that you dont demolish your selection ring by forcing it into the still faster-spinning driven gear and turn your tranny into a real expensive meat grinder.

Shift smoothly and deliberately - if you do this properly, the transmission will almost "suck" the shifter into the next gate - you should NEVER have to forcefully push the shifter into the gate - these are not 6 speed tremec's! they are econo-box transmissions that are slightly beefed up to handle a little extra power *for spirited driving in normal conditions*

Cool beans?

P.S. I do realize that some transmissions/shifters may not be properly set up from the factory, and that this is no doubt a factor in some of the pins breaking - so I am not putting the blame 100% on how people shift in some cases.

No it's definitely my fault. I am used to banging gears on a T56 in my Camaro. Just wondering who else does it too.

Not double clutchin' like ya should

Roll pins were designed to break so the part that it holds together does not. I hope that after they put that bolt in there that It doesnt end up breaking something else!

be happy you are only breaking rollpins that are external on the transmission. i have seen several times on mustangs (t5 trans), t56 in f-bodies (also used in many other applications) and even some trucks with short throw shifters were they break the roll pins holding the shift fork to the rail....inside the tranny. ive even seen broken shift forks from slamming gears with a short throw shifter. what causes it on rwd stuff is improperly set up shifters. most if not all rwd short throw shifter have stops that need to be set up to prevent the driver from overtravelling the rail and doing damage.

on the flip side, most fwd cars are cable shift, and ive never seen a fwd shifter with stops to prevent this damage. usualy before internal transmission damage happens either the roll pin in the shifter linkage breaks or the shifter cables break.

just some food for thought.

Naah. You are right. Its the drivers no doubt. 100% blame . seriously its awful that the roll pins get broken... and by the way i have seen Tremecs rubbished by drivers the same way...hacks, all of them. No other way to put it...

my 2nd pin just broke today n dealership isnt covering it but theres a nice how to on this site for it... so i will give it a try, i just wish there was a way to make it so it doesnt break again.... replacing the roll pin sounds like a bandaid fix i wonder how hard it would be to drill out and put a 1/4 roll pin or even a bolt as some people are doing...

Ralliartists HOW TO is very good. There is No room for a bolt and nut...more forum tribal knowledge bs. Even in Edmonton (still got snow? ) you can figure out how not to slam the shifter, thats what breaks them...good luck the how to works....

it's not a band aid fix, it's just how it was designed unfortunately. Testing on the new 08 turbo cobalt shifters will be done shortly, it may/may not prevent further roll pin breakage.

Broke 2 of them! Then found a solid trapered pin that we use to use on the old Hyundai Elantras that had the same problem and have not had a single problem in over a year. I used to know when it was going to brake because a week before the shifter would get loose.

when the shifter is loose, it's already broke, It just hasn't worked itself out of the hole yet. The dealer that replaced mine last time did a crappy job. Cause it was still sloppy when I got it back. After I replaced it, the shifter felt like brand new!
