how to improve gu auto gearbox

[Bigrig]

I ripped mine out - made a little difference to the changes (1000 ohm) mainly second to third, but apart from that, not overly noticeable - something we'll have a lash at again down the track once the new engine is in ...

Hi All,

Thread dig I know, but is there anyone in Perth willing to lend a hand doing this.

OR:

Is there a good write up with pics on how to do this with an 02 GU 4.8l Auto.

getting tired of the crappy shifts.

Cheers

If you've got the dollars, go the Nomad Heavy duty valvebody. Ive put one in my TB42 GQ and it shifts like a sports car A few others that have done it are also very happy with the result. Im in the process of talking a mate into putting one into his TB48

G'day all. My name is shane I have a 2002 wagon st plus 4.8auto 5 speed. I looked for the voltage resistor but cannot find it thanks guys

Has anyone ACTUALLY done this to a 4.8 GU, it seems more like GQ's here?

If so any pics etc?

Thanks in advance

Hi mate i know its been a while since you asked & you might have already sorted it out but ill put my 2 bobs worth in ive got a 98 4.5 gu second owner & i unplugged mine before i left the car yard the salesman had no idea wot i was doin. Mine is mounted on the drivers side firewall on the removable gold anadised plate where the clutch master cyl would be on a manual. Ive left mine unplugged for approx 6yrs now & havnt had a prob with it & im usually towing a car trailer i learnt about this mod with company vehicles i use to work on. Hope this helps

On my GU, i just keep the auto transmission swich on the centre console in "power" mode, doesn't this do the same thing anyway ?

I dont have a power switch either....LOL

You don't have a Power/Auto/Hold switch somewhere on your dash or centre console?
