428 cj and a cruiso need help

engine runs great but problems with ****** its a fresh rebuild and i can go threw all the gears and nothing happens at the rear end any suggestions

 

Ummmm..... Hook up a driveshaft???

 

You didn't hear a pop when you bolted up the transmission did you? If you didn't bolt it up right you could break the pump. Hard to diagnose with little info.

 

Did you mounted the converter on the trans first?
if you mounted it on the engine big risk of break the pump

do you have reverse?

 

does the drive shaft turn?....just sayin'....

 

Forget fluid?

 

the drive shaft is in and spins freely with the when i turn the wheels

 

i did not here any pop when on real easy i also filled the converter and put it in the bell housing before i put the trans on

 

i also bolted and torqed the converter to the flywheel after i torqued the trans bolts and the rear end is not froze up

 

any other sugestions i have been told that old trans need a little time to prime themselves i dont know this is my first trans rebuild thanks for answering

 

did you install the input shaft..it slides into the front pump...i did it a long long time ago will never do it again....

 

yes i did it was the first thing i put back in the case when i was rebuilding it and then after it all was together i put con,erter on and it slid on real easy once i lined the teeeth up

 

When you put the converter on, did you spin it until it seated on the pump?

 

Shift through all gears and check fluid level,With brake applied

 

Did the converter drop twice? A little at first and then again after spinning it some, also if it's not to much trouble drop the pan and check the lever, had one loosen up and then slip to the whenever put in gear.

 

i did spin it till it droped in twice i checked the lever when i put new seal in it . i am going to let it run tomarrow for about an hour and try it again i was told this will make sure all the fluid is nice and hot and threw all the lines and trans coolerhope this works i need to start to break in motor since it is a freash rebuild too

 

While the above statement is a bit scary, you did say you spun the converter until it moved back twice (once is clearing the seal, the second is the engagement of the front pump) so you may be OK. I'd bet on low fluid. Even though you filled the converter, there was likely a lot of airspace still in it that might have used up all of the fluid that was in the pan once you started the engine. How much total fluid have you put into the trans and converter?

 

i put 2 quarts in canverter before i put it in and the fluid level was rright at the bottom of the shaft that goes into the inputshaft and then i put in 5 quarts into the ****** i never draind the converter during rebuild cause the fluid was still good not burnt smelling or dirty

 

Loosen one of the cooling lines while running and see if you have any pump pressure. You will need this first to move. If no pressure and you have not been in the trans, probably a pump. If you have pressure, the valve body directs it to the correct area. See if the linkage is actuating the valve body. You should have something in one of these areas that is causing the problem.
good luck,

 

thanks everyone the help is great.

 

railroad the only pump is in the convertor right

 

i ran the car for an hour and nothing happened with ****** any ideas i am leaning to a new converter now but dont know where to start looking for one

 

After running the engine for a while, did you check the fluid level on the stick with the engine running? You said you filled the converter until the fluid was level with the shaft. That's basically only half full. So you would have used at least two of the five you put in the pan to fill the converter up full. The trans being a fresh rebuild is dry, so you'd have easily used up a bunch more of the fluid in the pan just filling up all the different hydraulic areas of the trans. A Cruise-O-Matic and it's torque converter have a fluid capacity of somewhere around 11 quarts. I still think you're low.

 

The dip stick tube extends into the case to shield the stick from splash oil so you can tell the level. I have seen people cut some off to get it back in then the oil level always shows high. One way to check it is to remove the stick with the engine running, wipe it off, be ready to stick it in and have someone shut off the engine. When it stops turning, quickly insert the dipstick and pull it back out.

I think those transmissions took at least 9 quarts of fluid or more.

 

No, the front pump bolts into the front of the trans, inside the bellhousing. With the torque converter out, you will see a round flange with bolts around the edges. I cannot remember for sure, but it seems there used to be a gasket lip around the edges. Anyway that is your pump. Sound like you did everything right with the install. If you have enough fluid and you have pressure on the cooling lines?? I'm still thinking the valve body linkage did not line up with the external linkage. If you get to the point you have to drop the pan, you can see if the valve body slide valves are moving with the shifter linkage.
The input shaft connects the converter and drive mechanics of the trans. If the fluid is getting hot it is being pumped. I just re read some of your input. Pull the pan before you pull the trans. If you pull the trans check the input shaft.

 

Ok ya I remeber that part t put a oring seal back in it. Ok I will check fluid level tomarrow thanks again I will keep informed

 

railroad when i put the valve body back in i put the shift linkage in the last spot on the slide and i put the kick down linkage between the stop and the slide was that right i think it was. thanks

 

ok guys i went out and checked out fliud levels and then i took off a ****** cooler line to see if i was getting anything and there was no fluid in the lines or in the cooler. so what now. is it the convertor or the pumps . i dont know how the pumps work so i dont know where to start thanks again

 

The spline on the outside of the front pump engages with the inside of the torque converter. It is direct drive to the front pump. Sounds like you are not pumping.
When and if you pull the trans, you will need to make sure the tq conv engages the
outside spline on the pump shaft and as you turn the tq conv, you are turning the
front pump. I am by no means an auto trans mechanic, but I have worked on my own.
I am a ford guy, so I have been around what you are working on. This is a long shot and
you may not want to try it, but I think the cruis o has a front and rear pump. This means you are able to push the car off to start it. Best I remember you have to exceed 35 mph to have sufficient pressure to transfer it all to the engine. In the event your front pump is the problem you could push or pull it off. Beware if you stop you are dead until the driveshaft starts to turn again. With no line pressure either the pump is not working or the valve body is not right. I put a shift kit in once and got no pressure. Problem was a c-4 kit into a cruis o trans, did not work,pump was OK. I just have not heard of many pumps going bad, unless they were run dry. I had a Ford o that a snap in tube on the valve body popped out and all the front pump pressure was lost, as the car coasted down a hill the rear pump made pressure and it was driveable, until I stopped and pulled the pan.
That's about all I got with the info.
Keep plugging and let us know what you are doing.

 

Thanks railroad will keep up to date I am going to call a trans shop on Monday. A budy gave me phone number so I gonna call and c what they say
