2005 ssr speedo fix

Post by brianc »

:evil: Folks I hate to keep asking but it has been 5 months since my speedo problems began and you keep saying you are working on the fix. ARE we any closer? Since I installed the 456 gears my speedo is way off and logging more miles then I am going. You have never answered my question about the car not shifting into overdrive at WOT. It will shift up if I let off the gas but will remain in 3rd gear until 120mph+ if I dont let off the gas. Please be honest and let me know if you are going to fix these problems or I may have to go back to the stock gears to fix these two problems, and believe me I dont want to do that as the gears are awsome. The tune is great but these two issues are NOT. Thanks

I have spent some time on the SSRfanatics site and have had a couple local SSRs here to test with, and have thus far been unable to correct the speedo.
Fortunately/unfortunately, this is not a problem soley on our end, as it would seem that ther is NO solution to this issue currently, as no other software seems to be able to correct this issue.

Either way, we have some truly talented people here working onthis, and we plan to figure it out eventually.
I do not yet have an ETA as to when this might be accomplished.

Thanks

the speedo problem is a software issue. The WOT 3-4 shift is a tune issue that needs TCM support to remedy BUT that is also the way the factory has set- as the factory does not support WOT shifts in the SSR, SS truck, etc. This is found throughout many GM cars because the trans is not strong enough to take the shock load of an O/D shfit @ WOT in a 5000 lb vehicle (as per GM warranty requirements for longevity) It can be corrected in the tune (with TCM support) but there is a reason for it, just FYI. The pcm will let it shift if the throttle is backed off to about 40-60% i believe, then you can resume WOT.
