Hey,

Wondering if, through the years I've been inactive, there's been a fix or accepted method of fixing the 'lag' or sometimes the failure to shift gears in tiptronic.

Driving my machine in D rarely makes sense, and 2nd to 3rd almost never changes when I tell it to.


Please spare your grounding kit myths- I'm grounded up the **** and it's had very little affect on my car and none so with shifting lag or failure.

Cheers!DOMO

 

I have the same problem. The majority of the times I take it to the track it rarely shifts when I want it to.

 

grounding kit fixed it for me, transgo shift kit sounds like what you need

 

I have a fully built 5AT. It's not a mechanical issue- it seems electronic.

 

I have sold over 500 of my custom kits and the reviews are 100% positive (check my itrader ratings). The kit will drastically improve the manual mode shifting.

PM me if interested.

Some people find that the grounding kits like the one sxexcx sells work really well (btw, dude's work seems great and is supported by many members), and for them its a low cost quick fix. Other people end up getting a VB upgrade. Transgo valvebody upgrade is probably what you want to search for if you go this route. Just a heads up though, the kit is not that expensive but the labor is what will get you. I would try the grounding kit first to see if it gives you what you are looking for.

 

I wont buy into grounding kits until there is scientific testing to it, placebo effect is a strong one.

I am not sure what OP is talking about anyhow my 05 shifts exactly when I tell it too, though of course there is some lag but its not that bad.

 

i was skeptical myself before purchasing a kit but the proof is in the pudding its everything they say it is..sean's kit made a serious difference, i know my car extremely well, especially how it shifts

 

When I get the shift lag feature our cars have, I just do the lazy ecu reset(remove neg terminal from battery and stomp the brake.) Go drive around the block and shift it a lot. It works for me.

 

Okay. Please read the OP.

I bought your kit years ago and it didn't fix my issue. I'm sure it still does what it's supposed to- but it did not cure this issue.

My tranny is FULLY BUILT. VB, clutch packs, bands everything- Congratsulations on the extra post but please read.

So again- besides grounding and building- do we know of a fix for this?

My battery has been disconnected multiple times

 

lol you dick, and if you've done all that and still have the issue its time for a new car...no further fix available

 

What is the shift lag reffering to? - I have a 5 AT and I have to give it at least 2 seconds between shifts, but it never has been an issue... I mean, from 5th to 3rd is def not like it would be in a manual, it goes to 4th and after 2 seconds I can go to third - does this thread imply there is a way to down shift and up shift faster ? - That would be cool just for the heck of it.

 

I've heard an Osiris Tune can fix this when they tune it.

 

^I have Osiris
Not only do I notice lag, but sometimes it seems like the power drops off for a second around 4,000/4,500rpm, then continues on as normal. I still have the stock transmission though so I'm not sure if my tranny is slipping or if its the tune. The AFR was normal when this happens. Anybody experience this before?

 

Sound to me like maybe a swap to 6mt is what he really needs.............
