T5 World Class Master Rebuild Kit - Suits All Ford Falcon and Holden Commodore World Class T5s
Every part you need to rebuild a World Class T5 properly, in one box. This is the full rebuild kit with the small parts added - the clips, washers, roll pins, shims and bushes that people forget to order and then wait a week for while the gearbox sits in pieces on the bench.
Kit includes
- Genuine Timken bearing set - front, rear, countershaft and mainshaft
- Synchrotech carbon synchro rings, 1st through 5th
- Input shaft seal, output shaft seal and top cover O-ring
- Shift fork pads, set of 6
- Shift key and spring sets for all gears
- Rear extension housing bush
- Countershaft shims and input shaft shims
- Shifter bush
- All roll pins, clips, snap rings and washers
Why the small parts matter
Roll pins and clips are single-use. Reusing a stretched roll pin in the shift rail or a tired snap ring on the mainshaft is how a fresh rebuild jumps out of gear six months later. The shims are the other one - countershaft and input endfloat have to be set to spec, and you cannot do that with the shims that came out.
Adding an input shaft pocket bearing
There are two types fitted to the World Class T5 and they are not interchangeable. Choose yours from the options above.
Not sure which one your gearbox has? Here is how to check in two minutes.
If the box is not stripped yet, select Not sure - contact me and we will confirm with you before we pack it.
Worth adding while the box is apart
- Countershaft cluster support / steel retainer - the alloy original cracks and lets the cluster walk. The common cause of a T5 that whines then eats a countershaft.
- Front input steel bearing retainer - replaces the cast original that wears oval where the release bearing rides.
- Billet 3rd / 4th shift fork - only worth it behind serious power. For a street rebuild the cast fork with the new pads in this kit is plenty.
- Solid billet 3rd / 4th shift keys - an upgrade over the sprung OEM keys included here, for boxes that see hard changes.
You will need fluid to refill it
A T5 takes ATF, not gear oil. Carbon synchros in particular need the friction package in an ATF to grab properly - fill a freshly rebuilt box with 75W90 and it will still crunch on a fast change.
We stock KCK RE44, and one 2.5 litre bottle fills a T5 with nothing left over. Here is why it has to be ATF.
Applications
Suits Holden, Ford, TVR and Sierra Cosworth World Class T5 transmissions.
Other kits
Do not need the small parts? The T5 rebuild kit with synchros covers bearings, seals, fork pads and carbon synchros. Bearings and seals only - the T5 minor rebuild kit.
Why buy your T5 parts from Racing Solutions
We rebuild World Class T5 gearboxes in house, and we stock the parts to do it. The part you are ordering is one we fit ourselves, held on our own shelf in Perth — not ordered in from overseas after you pay.
That is one of our own performance gearsets mid-rebuild. Over 20 years of hands-on trade experience sits behind every part we list and every bit of advice we give.
