I got a used transmission did the change in my truck. Started the truck and there was a grinding noise so I cut it off it was late so I went in. Contacted a few friends that said it sounded like the starter was staying engaged. Next day dropped the starter and a nut I was going to put on the exhaust and had dropped so I used another one because I could not find it. The nut had dropped on the starter and was laid against the bolt where the wire runs from the solenoid to the starter and against the side of the starter. Moved it tested the started did not seem to be working properly so I disconnected it and tested it outside of the truck and it worked the second try. Put it back in started the truck had the same noise but it quieted some so I put in reverse and it caught after a minute then stopped pulling then started back pulling. Exactly the same in drive. After doing some studying I feel one I did not seat the torque converter and two I attached it to the fly wheel before installing any bolts on the bell housing. I even had some trouble getting a couple bolts in but jacked the transmission up and down to align them. Please advise on what I did with the torque converter is my cause or if it is something different. I desperately do not wish to remove the entire transmission and drive back an hour to remove another one and do it all over again. Help!

If you attached the torque converter to the drive plate and then fitted the transmission, you may not have aligned the pump drive properly and this now may be damaged. You must always fully engage the torque converter into the transmission and ensure that it is fully home before fitting to engine. I do feel that the pump is damaged and the transmission will have to be removed.

So I need to remove the transmission and change the pump inside of the transmission? Or will I to replace the transmission itself?

Debris from the pump if it is damaged may go through the transmission and cause further damage and expense, I would look at the pump to see what or if anything heave gone wrong and make a determination at that point, the pressure of the pump drive not being aligned and the transmission being bolted up and driven, then the second failure dose not sound good, it is the way it was assembled that give me reason to feel that the pump drive is now the main problem, pull the trans and inspect this first.

Ok thank you so much. But I should say it has not been driven 100 feet since the transmission change. It was immediately making the noise when it was started after the change. The truck hasn't been cranked for more than 15 since the noise started. But yes at this point my plan is to remove the transmission torque converter and inspect the fly wheel carefully before tqking another step. Again thank you very much. Any further advice is welcome thanks.

The damage is done in the first revolution of the engine, its not about how far you drive it about turning the engine with things not aligned, even at idle say 850RPM, you only have to hear an odd grinding noise and shut down and the damage can be done, you don't get many second chances in this industry, damage is done in the blink of an eye.

Ok I took the transmission back out took the starter and flywheel off too because I couldn't see any signs of anything with the torque converter or the transmission. I found some scarring on the teeth of the flywheel and the starter. Please help me figure out what is going on. Not sure if it will be helpful but the reason I changed the transmission is when you put the original one in drive it took a little bit to actually grab and start driving like 30 seconds or more maybe a minute waiting for it to engage. Then when driving if you didn't take off very slow it would jerk and sound like gears were grinding. Then when it went from first to second it did the same thing.
I took some pictures to hopefully help you help me. And just as soon as I'm done spending money to fix this truck I will be donating to this page because you have surely been very patient and helpful.

Would the pilot bearing be inside the hole behind the flywheel or in the flywheel itself? I have not seen it and based on the first picture it doesn't look like there is one in the hole behind where the flywheel was. And if somehow the pilot bearing is not there could this be the cause of what is going on? Again thanks so much for your help.

Can I see I picture of the front of the converter to see if it fits into the end of the crankshaft?

I didn't think to take a picture of the front it has been put back into the truck now. I changed the pump and seated the torque converter properly. It hesitates to engage when put in drive or reverse. But shifts great after if engages. It was late and I didn't let the motor warm up before driving it. Is it possible this could be a result of the fluid not having gotten warm and moved throughout the entire transmission? I pray!
