Torque converter grab when idling in Drive

Posted by Cliff Johnston on June 14, 2021 at 8:47pm 2 Comments

Hi Everyone, been quite a while since i have been on here.

I have had an issue with the idle on my 64 Coupe Deville ever since i have had it.

With the Idle set high enough that it is smooth, but still a nice idle, the RPM seems only slightly too high for the stall of the Torque Converter. And therefore it tends to sit there and grab and lunge a bit. So until now, i have been putting the car in Neutral at the lights to stop this happening.

I've had the car dyno tuned and…

V.I.N. where?

Posted by Robert Pellow on April 18, 2021 at 1:41pm 6 Comments

Where can I find the V.I.N. on a 63 convertible?  The usual space at the base of the interior windshield on the driver's side has been decimated by weather.
