R31 S3 auto problems

[Dj laBBy]

Hey, I have an R31 series 3, aussie skyline with an auto.

I'm having troubles with the gear change between 1st and 2nd. It was apparently rebuilt and a stage 2 shift kit, however i put it in coz the change between 1st and 2nd was really bad(to me) but after the rebuild it was still the same. All the other gears are really good though and really clamp hard.

Could it be the fact of the auto computer not letting it change quick enough for various reasons???

If anyone has any thoughts or sugestions, please let me know.

cheers

Could you elaberate more on troubles? Is it slippping or is it slamming into second? if its slamming into second your servos have had the goose. Also so I have been told that when Nissan Aus bought them out they never adjusted the bands correctly, so that could also be looked at.

It seems to be really slipping from first to second, specially when the turbo kicks in.

Have had a thought that maybe it could be the module, as it is a standard vacuum one, am not sure, but are there pressure modules??? it just seems to be worse since it being turboed

From memory the S3 box is meant to have a decent firm shift from 1st to 2nd.

Honestly, in the long run, it will be cheaper and better performance wise to do a manual conversion. I did one on mine, it was quite easy actually.

The Jatco made autos that nissan use all have the same flaw.......slow shift from 1-2.I have modded my R32 auto to get a reasonable 1-2 shift only to cause probs elsewere.Manual is the only option.

Hey thanks for all the sujestions on getting a manual, would really like to, but i still like the idea of just cruising around with an auto, just getting lazy i guess, plus too it helps when my missus drives home from the pub. hehe

I remember an issue of zoom where brains used a 300zx auto computer, don't know if that might help at all, but hey might give it a go.

Will also get the auto shop to adjust the bands along with a few other things that they didn't do.

Thanks everyone for your help.
