Driving in D or OD?
Why? It's only going to go into 4th when you're at a proper speed to do so. I just run it in OD all the time...even when racing.
FWIW, Speculations and "I just heard..." have started more false thinking and downright wrong information on this and other boards that it has been difficult, at times, for the truth to be accepted.
There as sooo many myths about our 4L60Es running around that it'd take an hour or more to list them and then explain what the real story is.
It does't help when someone who says they work for this or that dealership/garage comes on here and gives incorrect information.
Not everyone has access to GM Tech manuals on everything. When you go to some of the others, you often get wrong/bad/mis-information.
I have had this happen many times when I had to use an 'aftermarket' manual on my '69 Mach1, '68 Javelin, etc.
