For a while, I noticed I was having really sluggish shifts between 1st and 2nd. So, 6 months ago I got a tuner to hopefully alleviate the problem. No such luck. The tune was from Eric Brooks for my '05 GT Auto w/ zero additional mods. We went back and forth, trying to see if it was an error in the tune, troubleshooting various things to no avail. After some time, I gave up. I returned my car to stock tonight to load a new tune later this weekend and noticed it was still doing it. The rest of the shifts are noticeably firmer than 1st-2nd. Is something wrong with my tranny? I know next to nothing about these transmissions. Is there a synchro that's notorious for crapping out other than, I think, 3rd? Anything I can do to troubleshoot?

Thanks in advance.

Call a Tuner like Brenspeed or JDM that run the 5r55s trannys.

Hmm, he may just be a lame tuner. I have seen a good number of autos that are still slushy after a regular tune from SCT or something. My Bama tune is the hardest/fastest shifting auto I have ever ridden in.. too hard almost. Chirps 1-2-3-4. Put up a video and we will be able to tell you.

I would suggest that you change your tranny fluid if you have not done so. Quite often sluggish shift can be contributed to the dirty tranny fluid.

I agree as well, and I know all about fluid. Your car is a 2005, and probably over 100,000 miles by now. Has the factory fluid and filter ever been changed? If not, that's your problem.

Get a tune from the auto experts and change your fluid.

Have you changed out the fuel filter lately? Maybe a good fuel cleaner treatment as well.
