MPHauto and I have been discussing the bad turn out of my transmission replacement thinking an improperly installed torque converter was my problem. I have taken the transmission back out along with the flywheel and starter. I have some pictures I will be sending. The only visible damage is scarring on the teeth of the flywheel and maybe the starter gear. Can I getbhelp on what I need to be checking to see what may have been causing the grinding sound when I started the truck before putting it into any gear and when it was in gear. As well as why it didn't catch properly when I put it in gear.
Also it may be helpful to know the whole reason for the transmission change to begin with was it took an extended period of timebto catch whe put in drive from park or reverse. So much thqt if on a hill I could roll 10 or 15 feet befoee it would catch. Then it would jerk when it finally caught and then when driving and it shifted from 1st to 2nd it jerked and grinded what sounded like gears then same with 2nd to 3rd.
Please help this has me so baffled and frustrated. I felt this would be a 2 day event then it took a week and turned out poorly.

I would suspect that the converter was not seated properly in the front pump and when you started the engine it damaged the pump. If you look at the nose of the converter you can see the two flats that slide into the pump. If those are not aligned and you tighten the engine to trans bolts down it will destroy the pump inside the transmission. With no pump the trans will not operate. None of your pictures will show the pump drive because it is deeper inside the trans behind the front seal and pump housing. The pic I added shows what the pump looks like, What can happen is that the converter not aligned properly will push the inner part into the housing and cause a pump failure very fast. The failure results in metal shavings being sent into the transmission.
It could be rebuilt and flushed, replace the front pump and reinstalled. The only way to verify this is to pull the front pump and check it for damage.

The pump has been replaced and I had to wait till monday to put the transmission back in. I am concerned about the torque converter I have drained it and see no sign of damage. But when I was moving it at one point I felt I heard something moving. Is it normal to hear this? It wasn't like a rattle or anything banging around just a slight noise.

The internals will move a bit until you install it on the input shaft. When you install it be VERY careful that it is fully seated into the pump with the two flats in the pump. Did you see any metal shavings or sparkling in the fluid?

No metal shavings or anything unusual. Thank God. And I am so grateful the sound isn't more trouble. Thanks so much.
