Working on a 78 360 Ramcharger with an A727. Had a massive leak. Split the trans and removed torque converter which had a badly worn snout. I replaced the converter, removed pump and changed bushing and re-installed everything. Other than the leak, the trans worked prior to starting the job.

After many hours re-assembling, i finally fired it up and topped it off, went through the gears to get the fluid everywhere. No leaks but now it only engages 1 and a Reverse. 2nd and Drive have a whirring noise but are not engaging. Seems like 1st and reverse are bound up too. With the wheels off the ground the wheels do not freely spin in either R or 1st.

Also, in park, the wheels do not set/lock as expected and still spin.

Any help or guidance would sure be appreciated. It has been a less than stellar day.......
