I am planning my spring upgrades on the Corvette and the Cadillac ATS.

I installed a Z06-style hood extractor vent on the Corvette, which is fantastic. It isn’t a night and day difference, but it is certainly more aggressive. The unit I installed from Extreme Online Store appears to be well-made. The paint job is nicely done and has a fairly deep clear coat. Time will tell whether the paint holds up as well as the factory vent did.

I also plan to install an EOS Stage 3 front splitter, but I am still undecided on whether to go with stage 2 or 3.

I had to change the transmission fluid on the Cadillac 8L90 transmission since it was displaying the low-rpm shudder common to many GM cars. The fix was a triple flush using Mobil 1 HP ATF LV. It was kind of expensive to “waste” fluid on a triple flush, but it is worth it to get it all refreshed. The dealer would have been at least $900. It took quite a long time because there were a few things in the way, but all was good. I filled it correctly after the final drain, using my Autel scanner to see the trans temperature to get the level exactly right.
