Re: If your 8spd trans is rough, put your hand up

Guys do you have this problem as an addition to the "roughness of the 8spd changes" that it holds 4th gear at 2500 rpm for longer (when it's "cold"...Qld summer starts), and to make it shift I have to push the throttle up to 3000rpm (which then sticks (b/w 2500-3000+)without me pushing the accelerator, and thus the car has its revs stuck there without throttle input from me) and then mebe it would shift upto 5th gear doing 60-70km/hr or I use the paddle shift to forcibly change the gear (but again the required revs are higher) and will not shift despite the shift points 15 min later are able to bring the car into 6th speed @60km/hr at revs of 1000-1400.

I nearly rear ended a police car yesterday , they breath tested me and what nots I had to actually prove I was having such trouble with the car and luckily I got off with a warning all because of this stupid issue.

Re: If your 8spd trans is rough, put your hand up

Finally got the valve body replacement, and I'm assuming the adaptive relearn process done, and now the shifting is 90% better in every mode. The best improvement was the abrupt downshifts. The shift points are the same but I seldom feel the 4-3 where as before I was feeling every downshift..and by feel I mean I was being excessively thrown forward from the engine braking. There's also zero 2-1 "kick" when you're coming to a dead stop and feel like you got hit from behind. ~200mi on the new valve body so far and keeping my fingers crossed that it stays this smooth.

Re: If your 8spd trans is rough, put your hand up

Diggum,
Would love to help you, but not sure what a rego number is?��, I have a 14 SRT, and my dealer changed the valve body on my first trip, they did a reprogram first, but concluded that didn't fix it so they got me a new valve body... Helped a great deal but trans still not perfect... Still drags on the 5-4 downshit, and rough 1-2 upshift on first upshift in the morning....

Thanks guys it would be a great help if you could

if possible I need the number plate of your vehicles (PM will do) that have had a change of the valve body and with it a change in the behaviour of the transmission

Re: If your 8spd trans is rough, put your hand up

Diggum,
Are you requesting the VIN number?
Vehicle Identification number
Thats what it's called in the US.... I'm guessing you live outside of the US, and may have another term for this number?
I'm willing to let you have mine, but perhaps by e-mail or private message

Re: If your 8spd trans is rough, put your hand up

I just got my 14 GC back from the dealer yesterday for a couple of recalls and I had them flash the tranny because of rough shifting. So far it feels better. I'll see if it lasts.

Re: If your 8spd trans is rough, put your hand up

My feeling it is the VB. Reason I feel it's that is that I have a stage 2 modified VB in my summer car. It is meant to do hard 1-2 and 2-3 with increased line pressure. That car shifts about the same harsh wise but because the 8 speed is hydraulic fluid and not trans fluid it doesn't compress as much making the shifts hard.

What does having a VIN do for you? Positive intent here, just trying to understand the info you are looking for.
