Where in hell are you driving your ZO6 on public streets, and able to be shifting from 4th to 5th at 5,500 RPM's?

It's only about 130MPH right? :rofl:

The Z can do over 100 MPH in 3rd. I can only imagine the speed winding out 4th! I'm going to guess its more than 130 MPH.

Exactly. I live in SoCal, and I've never driven the car in ambient temps below 60F yet, and most of the time the ambient temp is 70+. I also have never taken the car above 3.5k RPM until the coolant temp is above 190 and the oil is above 150.

(snip)

There is no question that my car has something horribly wrong with it, just like many others here, but I'm not going to take it into GM and have them screw it up even more, while letting them hold onto it for 3-4 weeks. I'll wait until they FINALLY admit what the problem is and post a suitable TSB or recall outling the proper fix.

I've been told 4th is a little bit over 160 :D

You are correct sir...although I haven't experienced it first hand,
mid 160's is the number. :eek::eek::eek:

My '08 Z06 is now sitting at the dealership waiting for tranny parts. GM is going to warranty the work, but took them a couple of days of negotiation to agree to this. They said tranny broke from me driving too hard. Not true. 5,000 miles on the car. Sometimes the gears would grind going into reverse. Embarrassing to grind gears in an expensive car. People are thinking I have an expensive sports car but I don't even know how to shift gears. Plus, it would not go into 5th when trying to shift above 5,500 rpm. I brought it to the dealership a couple of months ago and dealership said they couldn't duplicate the problem. I'm sure they tried their best. The problems remained and slowly got worse until it would no longer go into reverse at all. I am now relieved that it broke to a point where GM cannot deny there is a problem. I had been driving it for two months waiting for this day to come. Dealership tried to get me to admit that I race the car at the track, which I don't. I have one mod on the car, Hoosier R6 tires, which they assumed means I race the car. Our driving season up here in Canada is only about 4 months long, which is about how long these tires will last if you don't track the car. I need new tires every year, but man does this car ever corner nice with these tires. The stock tires really hold this car back. The dealer also complained that "What are you doing driving so fast that you are shifting into 5th gear at 5,500 rpm?". I didn't buy this car to just stare at it in my garage. I open it up once in a while and appreciate it's abilities.

Dealer had GM replace the tranny. Yay for me ...right? But I was told that there was a "file" on my car and that they were not going to replace anything transmission related because they suspect I am abusing the car. The car has never seen a dragstrip, was tracked once for 10 laps, spends most of the days in cruise control at 75 mph on the interstate...but I dont drive it like a Cadilac...:leaving:

I've got the grind in 2nd and 3rd, but only when it's cold. After the car warms up the problem is gone.

This forum chat is about bad trannys, don't fill it with your personal issues.

However, you are always welcome to join me for a ride. :D

Personal issues? I don't understand that, as much as I don't understand how you can be going so fast on public streets like you "claim"!

My story real quick:

2008 Z06- 9000 miles 4th gear synchros went bad (lots of grinding). Fixed under warranty. Got car back and started noticing it was difficult to get into first and second. Went on a trip...half way there the transmission went had to drive home in second and fifth (God bless 505 hp) Dealer had GM replace the tranny. Yay for me ...right? But I was told that there was a "file" on my car and that they were not going to replace anything transmission related because they suspect I am abusing the car. The car has never seen a dragstrip, was tracked once for 10 laps, spends most of the days in cruise control at 75 mph on the interstate...but I dont drive it like a Cadilac...:leaving:

Well, i feel for you guys. Got a new 09 after my 08 was traded for THIS EXACT REASON. Car saw the dealer 4 times (all trans related) before I got fed up.

Well, at 7K miles, car was in the dealer for 2nd/reverse and 1st gear grinding. W/E, it was "fixed" but i believe they left something loose and now it clanks. Great timing as the car is BACK at the dealer for clutch/hydraulic issues and I'm starting to notice the same thing in 2nd/reverse gears. Hard to shift, and all of a sudden... CRUNCH!!!!!

So, IMO humble opinion.... we have TWO main issues. Block out rings and our a weak hydraulic system that does allow the clutch to full disengage thus premature wear on trans parts. There is a reason we have to swap trans fluid almost ever other week due to contaminated fluid.
GM needs to address this instead of dumping their customers out to the curb.
