R33 Gtst - Improving Auto Transmission Response

[hardsteppa]

so winding up on the suspension work now, and thinking about the slush/lag of the stock auto box on the r33 gtst...would I be wasting my time fitting stiffer engine and transmission mounts and poly diff bushings in an effort to improve the throttle response of the auto box? Or is it just, it's an old auto, it's not going to be very responsive ever...Not looking to do a manual conversion but if anyone's fitted stiffer bushes/mountings and found it was worthwhile, would be interested to hear...

thanks

Only if the existing ones are loose. There's always a delay when a torque converter is involved, but on the plus side that's easier on all the components...

Depending on what you want and can afford. You could send the Transmission off and have it modified and strengthened.

If your 33 is stock then it's probably overkill and waste of your hard earned cash.

There is a cheap diy mod with a welsh plug that sharpens up the box a bit (just got a manual box myself).

thanks for replies. Not that keen on doing any upgrade work to the box, or removing it from the car...would be happy to replace some bushes if worthwhile but otherwise it will go into "too hard" basket...for a daily driver I will just put up with it!

Put a manual valve body in you will love it

oh ok, what's involved there?

Just put superpro front diff bushes in, slight difference nothing major, but then they were pretty cheap too. Loud diff whine now lol

Talk to mz autos in sa they will help you. Autos are more expensive to play with but when you drive a good one you won't look back

so I came up with the rocket-scientist idea of putting some solid rubber reinforcement in the gap that the stock gearbox mounts have, to stiffen it up a bit. I know what you're thinking, great idea dude, and it should have an effect between farrrk-all>>something at least.....while out of the car I noticed that my current gearbox mount does have some cracking and perishing of the rubber though. So started looking around for a new mount; seems there's a part number difference between the R33 GTST auto and manual transmission mounts though....even though they look identical in what pics I could find, so guessing maybe a measurement difference somewhere. Would prefer to fit a Nismo mount, but only seems to come in a manual application, not auto. Here's where I appeal to the community. Anyone have a manual transmission mount they want to compare vital measurements with? From what I can see, need to measure distance between mount>transmission mounting bolt holes, mount>crossmember stud holes, and width of gap that crossmember sits inside the mount. It'll make more sense with some pics; I'll post some up....
