    Default Best T5 rebuild kit for a 2nd gear grind?

    Have a grind going into 2nd gear, all else is great with the tranny, do I need a full rebuild kit or is there a smaller kit I can buy?

    If it's a world class t5, get a kit like this:

    and also pick up a steel bearing retainer:

    Depends on how bad and long it's been grinding. You may need a new 2nd gear and 1/2 synchro hub as well.

    Don't forget to order input bearing shims and learn the proper process to reassemble a T5 in regards to endplay adjustment. Seen too many T5s trashed because of people swapping parts and not really knowing what they are doing.

    One piece steel bearing retainer makes a big difference on strength.

    When you apply (relatively large amounts of torque) a T5 will tend to cause distortion/deflect at the bearing retainer. Any movement here will mess up the gear mesh geometry under load -- a great way to trash gears.

    ^^^Great advice here, I was lucky for years not understanding the importance of T-5 end play.

    At least 4 of the ~13 T5's I've killed over the years have been due to endplay challenges. Now I simply don't touch them - I leave it to the pros.

    My motor is mostly stock but I've never been shy about full power shifting. I somewhat blame the clutches I've ran at times due to cost being such a factor. High rear gears and wide rear tires probably also did not help ...... but a wounded T5 is a dead duck.

    What I can tell you from extensive experience is that when you can hear the input shaft clatter with the clutch engauged and the car in neutral and car running you can either heed the warning and take the car back apart to fix it, or it will take itself apart catostrophically in the next 5 mi - 20K mi. I've found there is no real way to predict which one it's going to be. It always ends with getting out the old checkbook and writing a bigger check than it would have been if it hadn't went crunch.

    Get a good clutch. Something with decently sized springs and friction materials for your power level.

    Zoom, Hyde, McLeod, RAM, etc..... are way better than $15 Mcparts.

    After doing it no no less than 11 times before getting told it was gone, i would not F with getting the flywheel surfaced. new duralast are cheap and WAY lighter than stock which makes a huge difference due to rotating mass. And they have a new ring gear on them which a reman starter will love while you are there. Or replace them one at a time and once it begins you will never get that nasty starter sound to go away....
