Default having issues joining trans to motor

So i put the motor in late last night but when i did it pushed the trans back so i pushed and pulled the trans while twisting the motor but it wont fully connect. there is a gap so that i can install the bolts.

I pulled the motor out and shifted the trans as far forward as possible and tried but it still gets hung up in the same place so then the motor wouldnt go in.


I notice that the nothes for the shaft on the trans has to be lined up perfect and i have tried as much as i can without pulling the trans out.

Is there and easier way.

P.S. due to the motor getting hung up i cant turn the motor over cuz it gets stuck on the trans shaft.

Is the torque converter fully seated? The mounting tabs should be 1/2" behind the face of the bell housing. Anything less than that means the converter's not properly seated on the pump.

If you left the torque converter on the flex plate, save yourself some grief: Stab the converter properly onto the front pump, replace the flex plate with a new one, and try again.

+1...... Sounds like the TC is not engaged properly. And have you removed the crank sensor?

i mounted the flex plate onto the motor then the TC to that. so you are telling me to mount the TC to the trans first then install the motor.

Right now a new flexplate isnt really an option it would take a week or 2 to get one and snow is supposed to fall within a few days so i want to get the motor running asap and get it in my garage about a mile away from where it is.

And yes the sensor was installed onto the motor, i forgot it the first time and realized its not really accesable to install after it was in so i pulled the motor about 3 min after the first install just to put the sensor in

Well sorry to say this but yes the TC goes in the trans, unbolt it from the flex plate and install it on the trans input shaft, you will need to spin it so you get it all the way on. Also make sure the TC has trans oil in it before you put it on the trans.
I would be looking at the seal on the trans and make sure you have not ripped it or squished it in any way from the TC.

Yes indeed, stab the converter to the transmission and ensure that the bolt pads are a half inch behind the bell housing face -- anything less and it's not properly engaged with the tangs of the front pump drive gear. If you crank it up with improper engagement you'll be pulling it out again shortly.

There's a pretty good chance that you boogered up the front pump seal, and maybe the bushing, too. Were it mine, I'd replace at least the seal. If it lets go you'll be doing the job all over again, so the little bit of bother and expense would be cheap insurance.

If you're lucky that flex plate will live. If you're not, well... you'll be doing it again.

I took the motor out and put the TC on the trans first. SO i put the motor in and bolted it down but havent bolted the trans to it yet im going to pull the trans out tomorrow after work and replace the seals although it never leaked the entire time the motor was out but better safe then sorry.

As for the flexplate i was very carefull with it and it should be fine i hope.



And after all that I will put it back

It won't leak from the front pump when it's not running.

Thank god you didn't try to suck them together that way with bolts. You'd have wrecked the pump and/or converter, maybe broken the bellhousing or stripped thread out of the engine block, etc.

For future reference, always unbolt the converter from the flex plate during removal and leave the converter where it's at. The only exception to this rule is a seized engine in which you cannot access the converter bolts.

ya i realize i should have unbolted it before, but when i took it out my buddy lifted the trans while i lifted the motor at the same time just to clear the motor mounts then i pulled it strait forward fairly easily.

But now the bad news is i cant work on the truck on the weekdays since ill be out of town for the next 6 or so weeks for work.(hate when they tell me 2 days in advance) BUt weekends should be free :0
