BA sluggish down low

[Z2TT]

Hi Guys.

I just got a BA wagon and 1st gear really doesn't seem to be anything great.  Before I had a VT Late model camira which was very peppy in 1st gear.  it's a petrol car
I know the falcon has a much shorter 1st gear but heaps more torque.  A friends BA Auto ute would fly off the starting line

I've seen other threads on different forums with some people asking the same thing.
I've seen AU Auto's jump off the line quickly.

Some guys mentioned the cable throttle holds back the car in 1st gear to make it more streetable hence giving the lag like feeling.

Is there any versions of the 4 Speed box that have a better 1st gear ratio I could swap in from any other BA or possibly AU?
Not looking into an option to just go a shorter diff as I only want to make 1st gear shorter.

The only other option is a ZF swap which is very expensive as wagons never had the 6 speed

Cheers

Yeah, you'll be looking for a gearbox change, as making a gear smaller but still engage properly won't be a cheap exercise on your current gearbox, but of course with money and time, anything is possible

 

It's pretty normal to feel slow off the line in a BA, especially if you compare directly to the equivalent model of bogan special.

Fair enough.  I'm not sure if there's a shorter 1st gear ratio I can put inside from another BTR box that can fit in the BTR box of the BA otherwise the only real solution is a ZF conversion.

Cannot I retrofit a AU mechanicals and re-use BA electronics?

no idea on that specific front. Probably best to speak to a gearbox specialist on that one.
