Last weekend i decided to tidy up some wiring under the dash of my R33 GTST S2 so i thought i would do the safe thing and disconnect the negative of my battery..it was disconnected for proberly 2 hrs but ever since i connected it back up my transmission is crap.

Now when i take off in drive from 1st to 2nd it near jolts your head off..from 2nd to 3rd it just won't change unless i lift my foot off the throttle a bit and the same for 3rd to 4th, even changing gears manually it does the same..i've done a search and found some members posts that have had sort of the same problem tried and checked all the surggestion made but no luck.

Fluid level is fine, theres no difference between a warm or cold transmission....would the ecu may have reset while i had the battery disconnected and now its not controlling gear changes like it should.

any advise or ideas would be great...thanks guys and girls

battery shouldnt have affected it, what did you do when you tidied up the wiring ? possibly you have knocked something loose. Check the Auto ecu behind the drivers kick panel, unplug and replug it and any other plug you might have touched inadvertently, might just be a loose connection from the ECU to the Auto ECU, speed signal eg

well i checked everything all looks fine...really strange and giving me the poohs...to get it to change from 2nd to 3rd and 3rd to 4th i have to rev it out to 3500 to 4000 rpm or lift my foot off the throttle each time i get a shit gear change.

would this be a job for an auto electrician or a transmission mechanic?

similar to a shift kit... just drilled out the oil holes in the valve body...gear change is more responsive but not to harsh

Interesting. Never heard of this before. So your gear changes are quicker and sharper, but it doesnt have the harshness of smacking into gear like a proper shift kit?

      braided lines for the turbos

      By GTSBoy · Posted

      For your application, where you'll be at that 1/2" size or perhaps larger, yeah, excellent. Although not if you need a tight bending radius anywhere, because the corrugated stuff is not anywhere near as flexible as rubber/teflon cored stuff. But for turbo oil lines? No. Too big. They just don't do the corro stuff down at the ~1/4" ID size that you'd want, and if they did the OD of it would probably be a bit too fat for fitting it into the tight spaces available. I use hoses like that all the time for fuel gases (LPG, NG) and liquid fuels (HFO, diesels, waste oils). When we did the London Olympic cauldron, with the 204 individual burners on it, we had miles of the stuff (although a lot of that was teflon core). A bunch of that crap is still cluttering up the workshop, more than 12 years later!

      Would something like this be an option  https://processhose.com/products/configurable-metal-hoses/1-2-in-t316-stainless-steel-annular-corrugated-configurable-flexible-metal-hose-assembly-with-ends-t304-single-braid-masterflex-af5550.html I'm looking at this for replacing the OEM EGR when installing a aftermarket intake plenum

      The once piece tail shafts with cv type joints on either end are the ones that end up vibrating and the vibration is caused by the cv joint binding as it turns, I’ve also seen them explode from the binding

      Take this with a pinch of salt, it's from someone (me) who got annoyed with turbos entirely. I hated aftermarket lines. If I had the option to use hardlines with whatever turbo I had - I would use them, 10/10, 100% of the time. The only reason people go larger, heat resistent, shielded lines etc is because they have to. And yes they don't last forever. Even if you spend big bucks on all the best heat shielding money can buy, with the best heat resistant, fuel resistant, oil resistant, radiation resistant hose, they get stiff and break down and just don't last the way a metal pipe will.

      Unfortunately I am quite literally halfway across the globe. So all sources for parts like that are far away for me. What do you mean by that exactly?
