Need some help, just swapped torque converters...

So my dad and I just swapped torque converters. Added a quart to it before we put it into the transmission. We seated it in and felt it click three times. Car starts every time with no problem. So, when we had the rear end up, we put it in gear and the wheels would barely spin. We gave it time and the wheels started to respond a bit more but not even close to where they should be. So, I checked to see if it was low on fluid and checked it in every gear hoping it would go down and I could add more. No luck there. Thought it was the linkage. Messed with that a few times. No luck there. So I'm running out of ideas. I thought maybe we damaged the pump(?), but I don't hear any out of place noises and I thought there would be no wheel spin with a bad pump. Any light shed on this matter would be appreciated greatly.

Thanks guys!

 

When I put my AOD in my Maverick it did the same thing. I finally took it out around the block and it would barely go. ran it up and down the gears and cheked fluid and it didnt go down. I pondered on it for a day or so. couldnt find anything wrong and line pressure was right on. Took it out again to see what it would do and decided if its broken then lets really break it and know for sure. so I started hammering on it and eventually is started to grab and then was all good. I think some air was stuck in the convertor.

 

I think that might be my situation. However, the wheels only spin when they are off the ground. Don't know if I forgot to mention that. If there is some air in the system is there anything I can do? or should I take of the TC and refill everything?

 

Hopefully PaulS will feel upto getting on the computer and giving you some insight. Sounds like you do not have any pump pressure, you did put the pump drive shaft in , right

 

uhhh I hope so(?). We took one converter out and put the other one in. That's it pretty much. Would the pump drive shaft come out with the other one?

 

It could but you would have noticed it. More than likely not the problem

 

I kept the other one and compared. I would like to the that would be and obvious difference but I can always check. Would the wheels spin if the pump was shot?

 

Mine wouldnt move at all either at first. I think after I ran ut backwards for a while I started to get some forward movement. I was pissed, I had just had the AOD rebuilt and couldnt figure out why it would go. I too thought my front pump was shot or that ithe convertor had slipped out a little when installing the trans.

Let it idle in gear for a while while on jackstands. hang out dring some beer, watch a game or whatever. then go drive backwards and see if it cleared up and will go forwards.

 

Ha if I wasn't too young to buy beer I would do that plan 100%. Ill do it with some soda. I hope this solves it!

 

I keep checking the fluid after it warms in park and neutral. And where does the hose run from and too

 

Hmm that might be a problem. That (or a cooling hose) was really stripped. We had trouble. Is that the one that hooks back with two 90 degree bends>

 

there are two different input shafts for c4s. i think one is 24 spline and the other is 26 spline. if you put a 26 spline converter on a 24 spline c4 it wont be able to move.
the only way to really check is to pull the trans and converter. you pull the input shaft out of the trans. its the shaft that sticks out the furthest. then you should be able to put it into the converter and feel it engage the splines in it.

 

The car starts just fine. So I'm guessing the converter has to move for that to happen, right? and when we put the converter in we pushed and turned and we could feel it sit in three times.

 

Are the trans cooler lines hooked up?.

 

They should be. Ill double check today. Maybe one came loose?
