C4

[camachinist]

C4 fill/start procedure on race car:

One quart of oil in converter. Allow to settle into converter spaces. Install converter. Pump is pre-primed with STP.

Four quarts of oil in pan (deep pan)

Car raised and level on cradle, lift or jackstands

Start engine, run transmission through gears, return to neutral or park. If no rear wheel motion, check and add oil until rear wheels rotate.

With engine running, check fluid level and add fluid until registering full. Run through gears again, re-check and add fluid as appropriate. When registering near full (in neutral), engage low gear, lock brake and run engine to 4000 rpm for ten seconds to build heat and check functions, then recheck and adjust fluid level. Check for leaks. Road test.

Got it all installed and even took it around the block after the whole deal of run, turn off, add fluid run again to check fluid, etc.

I do have an issue though and not sure what's causing it.

Seems to run fine.  Shifts fine, etc.

The only issue is when I got it home and back in the garage.

If I put it in park I can roll the car by pushing it like it's in neutral...any idea what's causing this?

Either the parking pawl is not engaging, or your shift linkage isn't quite right.  Obviously, try re-adjusting the shift linkage first before pulling the pan.

I know I thought I had it set right last night...of course it was about midnight but earlier today when it was in park it thought it was in neutral and reverse on the shifter was really putting it in drive.

I shut it off and readjusted the linkage and the neutral safety switch.  Each gear now seems to match up on the shifter.  With it in park would it be worth it to push further towards the rear of the car and then re-tighten the linkage?

Is there an adjustment that can be made to the parking pawl if the linkage seems fine?

[AzPete]

With everything adjusted properly, a car will roll a bit in one direction or another until the pawl drops into position for park. It should not move but a couple inches.

[RustyRed]

I hear ya..only earlier I could move it a measure of feet.

I put it up on stands and screwed around with the shift linkage some and it seems to be working now.

it seems to be working now.

Ah, and that's the important thing!  Congrats on it being the simple approach.
