My transmission is due from Detroit via Mexico sometime between now and the 17th. That will mean about 21 days in the shop +/-

You need to contact a lemon law attorney in your local market to determine your options.

Tomorrow will be the 9th day that mine has been at the dealership. They told me they are replacing the transmission, but I don't know when it will get there. They said it will still be 2 days of work after the trans comes in. I think Tremec needs to find a better place to manufacture...

My 4V BW manual transmission is currently at my local dealer in the air with the transmission out because something in the trans wasn't seated correctly when it was built. The dealer is either going to fix the transmission or replace it. I will find out which tomorrow. To say I am...

The dealer pulled the transmission and the clutch assembly looked fine. They opened the case and found that one of the internal parts was not seated correctly. They are checking on parts availability to see if they replace the part(s) or the whole transmission.

I dropped the car off at the dealership on Tuesday and they had gone back and forth with the engineers at GM for several days before taking action. One of the GM engineers said it could be a problem with the skip shift solenoid. I let the service writer know that the car doesn't have the skip...

I’ve tried HP MTF and it didn’t help so I went back to Dex III and it helped only a little. I went to the dealer today and had their “manual transmission guy” drive the car while I was in it. He agreed that it isn’t right and experienced the same issue with the car getting stuck in 2nd after...

It sounds like a trip to the dealer is in order. If they try to tell you your car is normal you can point to your experience at Spring Mountain to tell them your car clearly has something wrong after driving one that was not messed up. I’m very interested to hear how you make out. Please...

That is about what my manual 4BW trans runs at under similar conditions with normal driving. Even after running for an hour straight.

I bought 2 cases of HP MTF and did a change tonight after work. I test drove it about 5 miles and it seems to be an improvement. I will drive it more and get a better idea if it has made a real improvement.

Have you noticed any changes in shift quality? I swapped to Valvoline Dextron III because Tremec told me to use Dextron III and the Cadillac owners manual also said Dextron III. I have seen the HP-MTF article before but have been afraid to switch to it for fear of voiding my warranty.

I just got my confirmation for Spring Mountain Cadillac Owner's Academy. I will be driving a 4BW manual when I am there so that will give me a good comparison. I will also pick the brains of the mechanics when I am out there since they are exposed to a bunch of these cars.

Or put the factory pads or even something more aggressive back on for a track day. They are easy enough to change. The low dust pads are plenty capable for spirited street driving or carving up backroads.

I have about 1500 miles on my CT4VBW and the brake dust has been pretty bad. I started doing research on this forum and others trying to find a low dust street pad option. I have a C7 Grandsport that I put Powerstop pads on because the factory pads were too dusty for street use. On my...

Thanks for the replies. I did drive another 4VBW manual at a local dealer before driving to CT to get mine. The one I drove locally did shift better but the dealer wanted too much for it. My enthusiasm when I went to CT got the best of me and the temp was a bit cold so I didn’t think much...

Newt214, Do you have any updates regarding your transmission problems? I picked up my 2022 CT4V Blackwing manual transmission in January of this year. It had 15 miles on it at the dealer lot when I picked it up. I live in PA and drove to a dealer in CT to get it. I took it for a short...
