Anyone know what should be done to the ZF to handle 400-450ish rwkw? My input shaft carked it last week. Is a heat treated input shaft and upgraded clutch plates on the first few gears all I should need to beef it up a bit? The bloke at the shop mentioned an output shaft aswell as the torque converter and how much should getting this stuff cost? Ive had a look through what everyone else seems to be paying which is around $3600 for a rebuild, but he reckons it's going to cost closer to 8 grand to get them to buy the parts and fix it or 9K to buy a built box from BTA. Any help would be much appreciated.

Have a look at the ZF thread in Crescent Motorsport in advertisers section.

Stage 2 starts from 3999 which will easily handle that power (rated to 600). That's what I have in mine.

Lmfao @ 9k.

If you pay mote than 4k for a kit suitable for up to 600rwkw you're getting shaftes bigtime.

Call either joe from cms or rob from monstatorque. You'll be in good hands with either, and the builds are flex plate clutch packs and billet shaft.

HEY GUYS IVE GOT A BUILT ZF AND IT SHIFTS REALLY NICE JUST 1-2 AT LIGHT LOAD CHIRPS TYRES SAY 3000 RPM AND ABOVE AND GOING BACK FROM 3-2 IT WILL COMPRESSION LOCK IF IM MOVING FASTER THAN 40-50 KM/HR

IT HAS HITEC OIL IN IT ATM - WAS THINKING OF FLUSHING IT AND PUTTING TRANSMAX Z IN IT ... ANY OTHER SUGESTIONS ? A MATE HAS A BOX BUILT BY THE SAME MOB AND IT IS PERFECT / BETTER THAN STOCK SMOOTH AS AND SHIFTS AWESOME WOT

CHEERS LADS , JACK

Less caps lock dude lol. Has it had a ZF tune?

Fark - 2nd time you've yelled

Key above the left shift key is the first bit of advice I can give.

As asked above - has box been tuned?

Have you spoken to the person who built the box? Chances are he'll know exactly what needs to be done. He probably built it to your specs originally - just needs to adjust the build now that you've worked out that what you asked for is a little different to what you really wanted.

hahah sorry lol its a habbit at work lol I just asked for a box to handle 800hp and not slip and that's what it does... I don't run a zf tune as the box is firm enough as is

Has always had a bit of cold surge and seemed to get worse once PWR exchanger went on and gulf western syntrans went in. Loaded stock tune back in (ZF and engine) and from stone cold surge wasn't there. Auto felt better everywhere except firm change and omg, fart through the xforce - bloody loud! When going more power I was thinking of pulling a bit out of the tune or removing it altogether. What I'd really like is to keep a small bit of spark cut but have been told can't adjust that. Thoughts?

Ummm I have reduced torque reduction as part of my tune.
