A bloke at work wants to put 35s on his mq short, pretty sure it is diesel and wants to keep / improve his low range gearing

He realy wants to do something along the lines of t-case gears but apprently you can't buy any.

What advice can i give him, we have already thought of adapting twin hilux transfers into the shorty :twisted:

low gearing wasn't that bad with the 35's, 33's didn't even notice it but up to the 35's you will be surprised... it's not that bad

I run 35" BFG MT's on mine and 1st is fine for crawling....will be a bit better when the 5spd goes in but !!!!

I thought all of the ratios were the same as a 4spd except 5th is obviously higher....?????

Is it possible to tell from the outside which 5 speed you have?

the numbers stamped on the front top edge of the G/box are a code as to what box it is ( right up near where the bellhousing bolts up), other than that pull the sparkplugs out and with a mate rotate the motor in 1st gear and count the revs the driveshaft turns ( put a mark on the shaft)... its the simplist way and gives a fairly accurate reading. or PM me the numbers and I'll check it against the book.

V8, what was the ratios for the 3spd

Post by **MQ080** » Fri Sep 12, 2003 2:20 pm

BTW i thought that the MK's only came in an SD33T but are you saying they still retained the SD33 with the 5spd box?

I dont know about the MK series motor/box combinations but the MQ series 1980 to 1987 ran a couple of different combinations in gearbox's and transfers to both the SD33 and SD33T aswell as different suspension setups/ interiors/seating capacities etc, multiply that by the LWB & SWB and petrol/diesel models and you can see where the confusion starts to set in !
Of my 3 MQ's alone there are 3 totally different combinations, ChevyMQ has 3 aswell and his are also different aswell, even the diff ratios are different in 2 of the 6 MQ's here and they are all SWB vehicles !!!
One I cant figure is the seating capacities of my 3... one compliance plate says 3 , next says 4 and the last says 5 !!!! go figure that one !
As for the 3 spd ???? the bible doesnt have any ratios listed but I will check out a bloke I know who has a full set of microfish on patrols and get back to you.
