All Small Six Camshaft break in and transmission fluid levels

[clochard68]

My C4 automatic got a shift kit and new oil pan.
I reinstalled everything and filled the transmission up to the full mark. It sat for almost 2 years now. With my new camshaft there are a few questions that are critical for a (transmission-) safe break in:

When I break in my new cam, do I just check the trans fluid level while breaking in and add fluid if it gets to low? Or do I overfill it at first?

Is it even possible to check the level when the engine revs around 200-2500rpm?

Do I keep the transmission in park or in neutral?

So many questions I am sorry but I want to keep the C4 healthy

The camshaft breaking in doesn't really have anything to do with the transmission, other than making sure the transmission is in Park while you're breaking in the cam (20-30 minutes at a steady 2500-3000 rpm is the standard). I would suggest putting a zinc additive in the engine oil before you start the break-in process.

As far as the transmission, the fluid should be checked after the transmission is warm (the engine has run for a while, as in after a cam break-in). If it shows low, then add until it's in the proper range on the dipstick. You should avoid overfilling.

Thanks John!

Then I will leave the transmission in Park and check levels as you suggested.

The transmission fluid level has to be checked with the engine running and at operating temperature.

Yes! Thank you for stating that - I didn't and should have.
