can't bolt tranny up to engine?

I have a 1969 c4 tran (auto) and a 1988 5l HO engine that came out of a 5 speed standard mustang , when i go too bolt up the two the torque hit the center of the engine and thats stops me from putting the two together. Is there away of solving this problem.

Thanks George

 

Are you sure the torque convert is seated down all the way? Sometimes you have to spin it around a little and screw with it a little to get it seated. Also, not sure if it matters, but did you remove the pilot bushing from the end of the crank?

 

Make sure your torque converter is seated completly onto the transmission. If its not and you try to force it you WILL break something.

 

no i didn't remove the pilot bushing, should I ?

your converter is probley not in all the way and the bushing really don't need to be out it wont be in the way

 

is there anyway of putting on the flywheel on backwards cause when i put the converter upto the flywheel the center of the converter hit the engine and the studs will not go through the holes on the fly wheel

 

might need to check and see if they gave you the correct...flexplate...
is it the right converter? will the holes line up with the flexplate?
what motor did the c4 come off of?...

the was a 69 302 before I replace with a 5L ho

 

As stated in Jamies reply you must take out pilot bushing from center of crank and the flexplate you will need will be a 50 oz weighted one instead of a 28 oz one like would be on the 69 c4, cant really put the flexplate on backwards as it would hit motor plate. Torque convertor should click three times to be all the way seated into transmission and back from face of bell housing about 1 1/8 inch. Dont try to force tranny into place or you will damage pump.

 

yellow my pilot bushing is still in my crank and it has not caused any problems and I am running a c4 also Is that bad should I take it out? I left it in because I wasn't sure I was going to stay with a c4 our not and it didn't rub on anything

 

What is the torque convertor out of? Is it the original one that was in that transmission? 1969 was 24 spline input. After 1970 they went to a 26 spline. If it is the right one make sure you put the Convertor on the shaft and it should bump down t times as you spin it slowly on.

 

Is the flexplate a 157 tooth or the 1988 164 tooth? 69 c4 would need a 157 tooth flexplate with a 50oz balance. I believe this is a non-stock aftermarket deal only.

 

Just a clarifying question.. you called it a flywheel... the motor is from a manual trans car.. you did replace the flywheel with a flexplate right? And no, you can't put them on backward and get all the holes to line up. Regarding the converter, if it's the one from the tranny, along with the bellhousing, this doesn't apply, but they are not all the same length. The converter for a large bell (164 tooth flexplate) is longer because the bell is slightly longer.

 

stangclone if you left the pilot bushing in and everything is still working then it must be okay or else you would have never got the torque convertor to seat far enough in, either that or you pulled flexplate back to convertor. I just did conversion from stick to auto and put my convertor up to my flexplate before trying to install tranny and the convertor would not seat against flexplate because of hub of convertor hitting pilot bearing, Maybe PaulS will chime in on this he is wise on these things
