[brendo4b]

Has anone ever broke a gearbox behind a td42 i have one that ive had in a petrol patrol for the last 322000 it was originally my grandfathers and only ever towed w caravan no real hard work i have given it abit of shit since ive had it a few small burnouts and some minor 4x4 i am doing a trip around oz next year and tossing up whether the give her a rebuild or not what are your thoughts are they a good tough box cheers

[stool]

Should be fine as they are a very strong box

I have one behind my 7.4L chev with a brass button clutch
and 35" tyres and it still lives after plenty of testing so to speak

Seen Many Break, Big HP deisels but.
Robbie Marshall had a colletion of broken gearboxs.
The average TD42 aint going to break one but they are not unbreakable.

rebuilding the gearbox won't make it any less likely to break due to power. the stress from being behind a powerful motor adds up over time so that it's likely to break when put under heaps of stress.

we are talkin manual here right?

Ive seen more than one shit 5th gear from towing in top gear. My mates ended up been able to only get 3rd, but was just all the bits fromk 5th jamming everythin up

[mq_camo]

my first gear has shit its self i can only take off in second unless i jam it into first while rolling, got a quote to get it fixed and the stooges want approx 2 grand, i run 35's and 20psi in my gq ute and i dont even really give it a hard time.

Stripped the synchros off third gear with a 351c and a mate has done the same with a chev.

Besides that they're very strong boxes

I didnt break mine but would of if I left in much longer. All gears except 4th sounded like a grinder and would pop out of 3rd on decel as well. I have a TD42 with a turbo and 35's so no they're not indestructable. I put a GU box in it about two and a half years ago and it's been fine.
