Ok, this is a new build, new motor, new trans. Everything works great. Put the trans in D and you can move forward, put it in R and truck will go back. Put the trans in N and you can rev it up, put it in P and you can rev it up. Then kill the motor, and I can get out and push the truck like it is in N. What is going on? Park isn't locking up. What could cause this? My fluid level is great. I haven't gone on a test drive yet, but I want to soon. The trans goes into forward and rev gears great. Goes into N great, and you can rev it up in park, but the truck will still roll in park.

Any ideas?

I'd check your linkage adjustment...
Park lock is a macanical locking ring.. and has nothing to do with fluid. unhook your linkage and move the tranny into park and then put the shifter in park and see if they line up.

Who built/rebuilt the trans? The park pawl may have been left out! It's a mechanical lock - a metal tab that clicks into a notch on the output shaft.

The parking paul not engaging ot broken is definitely your problem... Take it back to the builder immediately....

Several things possible. ALinkage adjustment, parking paw broken or left out, the locking gear on output shaft not put back on. It slips over the output shaft and has a locking ring holding it in place. You can actually remove the tailshaft housing, after you remove the drive shaft and see what's going on. Rise the rear of the cart as you get ATF out of the housing when you remove it. Could be just a snapring was left out allowing it to move away from the paw. You can see the linkage work with the housing off also.

I'm going to disconnect the linkage and try and put the trans in park at the transmission. If the truck still rolls then I will starting pulling it apart. I've got a spare big block C6 that I can compare it to or rob parts from.

thanks
