I recently rebuilt my 2wd tranny from my 00 sierra went fairly well but I put the tranny back in the truck and went to put it in gear and the shifter reads different and the tranny does not in gauge with any gear at all no reverse no forward and the the column shifter will not go to 2 or 1 on the dash what did I do wrong

 

Possible misadjusted shift linkage or Park/Neutral Switch on the side of the transmission. I like the adjust shift linkage with the shifter in neutral and the shift lever on the side of the transmission in neutral. Linkage or cable should slip on the transmission lever without pulling on the linkage or lever.

 

ok I can see doing that but would it also create the trans to not engage at all cause no matter where I shift the tree to there absolutely no movement at all from the trans not even a bump I get no action at all

 

first and foremost make sure you have enough fluid in the thing
Didn't forget the filter did ya?

 

When diagnosing I almost always repair the things that I know are wrong 1st and that a lot of times takes care of the problem.
You can hook up a pressure gauge to the trans or unhook a cooler line and start the engine to see if you have fluid flow.
You can remove the pan and check that the manual valve is connected.

 

ok thanks a lot for the info I’ve already pulled it back out of the truck again but I’ll open the pan and take a look to make sure everything is still connected properly before I rebuilt it it had shifting issue from 1st to second so I just figured go ahead and replace all the clutches and plates figured that would take care of my problem but it only made it worse off

 

fluid full and filter in place so I don’t know what could be the issue could I have damaged the pump somehow or maybe something in the valvebody

 

with converter pushed all the way in what was clearance from converter mounting pad to flywheel? if there was none maybe you broke pump when you bolted bellhousing to engine.

 

Too much band clearance will create a no 1-2 shift. Follow attached instructions on how the check and adjust this clearance.

 

I honestly didn’t pay it no mind I was so frustrated from laying on my back putting it back in that I wasn’t paying attention how would I find out if the pump is busted this I my first go at these trannys

 

thank you for the info but I have a no shift at all problem it just won’t engulfs at all in any gear

 

Why would you try to diagnose a 1-2 problem when it has no movement....

 

I wasn’t trying to diagnose a 1-2 problem I’m trying to figure out what I did wrong when I rebuilt the tranny to make it not work at all

 

Because he said that he rebuilt the trans in the 1st place because of a "it had shifting issue from 1st to second" and since the trans never moved once reinstalled he doesn't know if that problem has been resolved. Also, from the looks and sounds of it he just through in a seal kit and set clutches and call it a rebuild. I was giving him some information so that he could maybe at least ensure he has a 1-2 shift if he is able to find and repair the bigger no movement problem..

 

put a pressure gauge on it

 

Don't laugh, these are things professional transmission guy's have done/seen over the years.
No movement at all.
1) extremely low or no fluid. Should be 13qts if cooler was flushed.
2) missing converter or converter bolts
3) broken pump gears
4) broken input drum
pull a cooler line and see if you have some flow. Top line at radiator is return. Rig up a hose to go into a bucket. Have someone start the truck. No flow in 3-5 seconds means it has to come back out.

 

Sadly, he has already pulled the trans, so hopefully the problem is obvious.

 

When I put the tranny back together I forgot to put the bearing spacer in. Which resulted in the tranny not being able to spin freely. Which in turn shattered the the paddle wheel in the pump. And also the check ball for drive reverse was stuck in the valve body. I’ve replaced the pump and got check ball freed up and tranny worked perfect. But now I have a whole new issue going on. But thankyou everyone for your feed back

 

Thank you for reporting back.
