4th gearbox lucky.....

[Danhart]

Fitting my 4th and fin box tonight, got myself. Low mileage, 40k f18wr, fitted the LSD I had previously purchased, just ready for fitting tonight,

Anybody want I have a guess on how long it'll last, bear in mind I do not rag it through gears, but I do allow it to pull from say 1500rpm
last box only did 3 weeks, but did have 100k on it


Should get round to putting the half shaft conversion on too as I find torque steer on the 1.7 to be something quite silly!

Shall be be removing intercooler from my cdti van too for the nova then it's just a clean up for billing!

What are you doing to them to kill them?

I've only seen the GM boxes fail due to overly keen shifting and a 5th just giving up.

Where are you? I'd like to open one of the dead boxes up for interest :)

My mate chewed through 3 f20's with a basically standard 20xe. No idea how

Its always 5th what gives up, 2 have just been teeth stripped, one actually snapped the gear off,

always seems em stop be when pulling hard from low revs

i did 5th in my v6 lol

Its the low revs and massive torque from the TD that's eating boxes, TBH I would have fitted an stronger box and been done with it.

As said I've got with an other f18, shall see what happens but I do have ideas for better boxes

I have considered this, huge in size, and I guess the gear cluster cannot be swapped into my f18 casing so a mount would need to be made
