Re: C4 won't shift into 3rd gear when cold

Hey Paul,

I tried the Seafoam additive just for the heck of it, drove it around for 10 miles, let it sit over night, and still no sign of third gear for the first mile when cold. No big surprise, but I thought I'd try it anyway. I did however notice this time that when it is cold and hanging in 2nd gear while in the drive position, when it shifts to "neutral" instead of 3rd gear, if I mash down on the throttle to about 4,000 RPM it will suddenly drop into 3rd gear and chirp the tires with a good firm shift. There is a bit more intel for you to consider; it will shift into 3rd when cold, I just have to get the pressure high enough by revving the motor real high. When it does shift into 3rd gear it is super crisp, no slipping at all. And when it warms up after a few miles it shifts through all the gears normally in drive.

On a side note, I think my MSD6AL ignition box crapped out on my last transmission test drive -- the car was running great, I hopped on it at a light and shifted hard to 70. Came to the next light and suddenly it just died, started right up, then died three times while I was driving it home, then the 4th time, it starting missing and losing power, I barely got it back to the garage and opened the hood before it died again and now it won't start. It has spark, but it is weak at the plugs, it will try to start but it won't actually start. I'm pretty sure it's the MSD6AL.

LOL

So much for cruising this weekend :-(
