My car will not shift down while in sport mode.

Ok so my deal is exactly what the title says. While I have my G35 in sport mode it shifts up just fine. The problem is it will not hardly ever shift down i have to come to a complete stop to get it back to first gear. I called the dealership they said they didn't know what it could be. Car is not under warranty any longer so having it repaired that way is not possible. Anyone else ever had this issue and if so what was the solution.

Are you new to tiptronic cars?

Sounds normal to me. Your car should not shift down to 1st unless you are going < 3-5 mph less you damage the transmission.

I have never drove a car like this only regular standards I have drone. So it is new to me but i'll give it a go to try to shift down at a lower speed.

It should shift down normally to 2nd when driving slow, but like the others said...almost never to first until you come to a near complete stop.

Well the main issue is I can't get from 5th to 3rd when I'm running about 35 MPH. Especially when I do a hard excel

It does downshift sometimes while in sport mode. But most of the time no. I am shifting within the listed parameters. It also shifts just fine while in normal drive mode. But if I put it to Sport Mode it hardly ever shifts down.I have to pull it back and back and back to get it from 4th to 5th at speeds like 20 MPH.

Definitely electrical issue, start with the console module. Any junk yards in the area?

Can you please explain what Sport Mode is? The G series cars have never had a sport setting...we don't have a sport buttom.. So I am unsure as to what Sport Mode you are talking about...

It is when you put it from auto to manual. The dealership here called it sport mode so I assume that's what it is.
