2009-2015 Cadillac CTS-V Performance Mods Discussion, Transmission Issue in Cadillac CTS-V Series Forum - 2009-2015; So I got my car tuned a few months ago and love the tune, makes 510whp and it barely changed ...
So I got my car tuned a few months ago and love the tune, makes 510whp and it barely changed the shift patterns....that being said yesterday I manual shifted it to 3rd and hit it and it was probably the hardest pull I've felt the car do, then after coming out of the gym headed home it started shifting aggressively and when coming to a stop down shifting aggressively. Then it got to where it wouldn't shift into 5 or 6 even in manual mode. Took it to the dealer and they said what I expected...take the tune out of it. But I don't think it's the tune. For some reason at the dealer it didn't do it, then when I picked it up it started again (figures). I figure I'd wait for it to throw a check engine light again so they could pull the code next time. Any ideas?
Inside the transmission 4-5-6 share the same clutch pack But 5 shares another clutch pack that is the 2-5-R. Usually if you loose 4th to 6th gear, it is just the 456 clutch pack. However, what you are saying doesn't sound like aclutch problem at all.
does your issue happen if you put it in normal mode, or performance mode or both?
Maybe get the person to put your stock tune in it and see if the problem goes away. Not sure what else you have for mods either but 510 sounds really high if you are all stock.
It happens when I'm in automatic mode then if I put it in manual mode to try n shift to 5 or 6 it just blinks at me. All I have is a CAI and a tune and I was a little off on e whp it's 507. Not much difference I guess. I think I'll ge the dealer to flash it back to stock on the transmission and leave the engine tune like it is. I had to get it tuned to to buying a Hennessey CAI. I should have went with an Airaid.
Well I'm not sure if it works normally after it sits really but I know that of a tech gets near it it works perfectly. I guess I need a Cadillac tech to ride around with me all day. I've got an appointment for it Friday to wipe out the trans tune and see what happens. I'm hoping it will throw a code again so they know what they're looking at.
blinking means override meaning as in the conditions needed where not met. How fast are you going when you are trying to put it into 5th or 6th. There are speed and throttle values that have to be met for a manual shift to be allowed. Meaning when you are a complete stop, every car will blink if you are at a stop and try to manually go past 3rd gear. It will flash, however if you are moving past 30mph then it will allow all the way to 6th.
Haha, yeah I know. I was going about 50mph in 4th running around 4000rpms and it needed to shift up but wouldn't. Now it's been doing fine for the past few days for some reason. Maybe it just went into limp mode and now it's back to normal. I got the tech to add another quart to it.
