i got a gq patrol with 4spd auto. well looked after gearbox no issues with it at all, but looking to improve it now that im running big tyres its alittle sluggish, looking to increase take off in it like when going up hills or just general driving before i just go spend money go turbo or v8 conversion.
im not sure what recommend but thinking about a stall converter, atm you can already lock it into 1st gear but i maybe a upgraded manual control lock-up unit, and valve body upgrade?
what else do yous reckon, also im located in brisbane so if anyone can recommend me to anywere to get the work done to it?
