100 series auto question

[kevdog]

so i am going to get a service done on my auto... (99 model 105 series... a442 box i think)

anyway has anyone done an upgrade on the valve body and how did it go?

i was thinking of doing this at the same time to save a bit of cash (maybe).. i read on another website that this alone will improve shifting...

thoughts?

Had to put one on my turbo 4.5 then took it iff and put it in the turbo diersel later, good firm shifts, costs 800 exchange and easy to do if you are good with spanners, otherwise the local guy can install...

I put the "Wholesale Automatics Extreme Valve Body" on my 2002 FZJ105R GXL 4.5 petrol/LPG, with the A442F auto.

Overall I'm very happy with it.

Benefits:
- Better power down, no slipping or hunting around
- Seems to be more direct - as in the throttle-to-road-speed takes much less time. (Could be imagination, or a side-effect of the firmer shifting)
- Engine braking is greatly increased for some reason - it now doesn't run away from me in low range down a hill.
- Tows a 28 foot boat out up a ramp far easier now, doesn't struggle
- Firmer shifting means it doesn't search around for a gear, it selects it and goes.

Detriment:
- Harsh shifting when under power - it can shake the whole car. I get around this by knowing when it usually shifts, and I gently back-off the accelerator pedal until it shifts, then put the boot back in smoothly.
Takes most of the harshness out of the shift.

Hasn't increased power, but if I wanted to turbo my 4.5 (I _WANT_ to, but can't justify the $$$'s) then my A442F with the valve body would handle it no problem.


If you're around Canberra, I'll take you for a drive in my rig so you could make your own mind up.


I haven't put the auto trans temp guage or the manual overdrive override (shift lockout) switch in yet - haven't gotten around to it in 6 months so don't think I'll bother...
