iitzHarro Posted May 9, 2022 Share Posted May 9, 2022 Hey fellas i was wondering if anyone could point me in the right direction. My fg ute has 3.73 diff gears behind the 5 speed auto for now, ive changed all the axles ratios and got my speedo spot on again, but under WOT its still hitting limiter no slip or flair yet lol just doesnt shift in time. i was told the 5 speed utes read speed from trans instead of rear abs sensors, so im unsure what i should be looking at in the trans shift points is it speed or rpm ? what should i be adjusting. any helps greatly appreciated Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted May 10, 2022 Share Posted May 10, 2022 Raise the rev limiter by 200rpm. Quote Link to comment Share on other sites More sharing options...
iitzHarro Posted May 10, 2022 Author Share Posted May 10, 2022 cheers mate should i also bump fuel cut up 200 rpm ? sometimes it hits hard enough to fall on its face and id assume thats probably really bad for it lol Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted May 10, 2022 Share Posted May 10, 2022 Sure, I would. I only suggested it to avoid hitting the limiter in auto mode, not to use more rpm in day to day use. When you're flooring it you should be shifting manually and with practice you won't hit the limiter. Hitting the limiter is asking for an oil pump failure so take care to avoid it where possible.

iitzHarro Posted May 11, 2022 Author Share Posted May 11, 2022 i tried the rev limit things its still bumping redline haha i found some WOT shift points at sea level and they are all set to 6k rpm might try reducing them 500rpm see if that helps. is sports mode tow/haul mode ? cheers for the help fellas its greatly appreciated also im mainly trying to fix it so when the misso drives it she doesnt bounce it of redline lol Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted May 11, 2022 Share Posted May 11, 2022 (edited) Changing the shift points is what you should be doing but usually a rev limit change by a few hundred rpm does the trick. A quick and easy way to change the shift points is to go through all the shift maps except 27, and change the whole map by a percentage. It's not the perfect way of doing it but it'll give you an idea of what the box is going to do. You'll find this stuff in "ZF Shift \Lock Schedule" Edit: That's where it is in the zf6 file, I haven't looked at the 5 speed file to confirm.
