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.......

No park? Is the transfer case in neutral?

I tightened the kickdown band before pulling front oil pump and then re-adjusted it prior to firing it up.
.... Never took off pan or touched anything other than front pump (to replace seal and bushing) and kickdown band adjust. I am thinking that since you didn't pull the pan, the only things I can think of are: 1) Front drum with clutch pack not engaged correctly when reassembled (as somebody mentioned). But typically cannot get things back together if this happened. 2) The rings on the support or input shaft were damaged when reassembled. Leaking fluid passages to wrong places.

Sorry, I read your first post that you did a complete when all you did was pull the pump.
So, for the ratcheting - sounds like you still have something wrong with the shifter. Move the lever all the way forward, then count how many detents you need to get to park. 1,2,D,N,R,P = 5. You need to address that first. Until a shifter is properly adjusted you should never do any diagnosis or repair.
If you installed the pump with the front band tight you likely damaged the input shaft seal/s. Like 440Jim mentioned, you may have had the front drum move forward when you pulled the pump then when installing the pump you crowded the first clutch disc and bend the teeth.
If you damaged the large reaction shaft seals you shouldn’t have a strong reverse.

I was going to say - if it grinds the park pawl going into park, the output shaft is turning. If the output shaft is turning and the drive shaft is not, the issue is between those two. Sounds like you found that out.
If the results don't match the theory, change the theory.
