Thanks to all of you for your input. I live in a growing city of 70-80 thousand people and not one parts house had pennzoil synchromesh or had even heard of it...go figure. I refilled the transmission with atf and it meshes gears much better than it did with the GL-5. I will find the synchromesh oil and replace the atf with that product. 69y2RT recommended Mopars version called synchromesh also. I will try that if i don't locate the pennzoil product. The cold isn't an issue as I drive the Dart mostly in the summer. Thanks, again, is this the best site for information or what?!
