Three most likely causes are: #1 You forgot to tighten up all the torque converter to flex plate nuts/bolts. #2 You cracked the flex plate during the transmission change. #3 You forgot to swap one or both of the alignment dowels from the old transmission to the new one during the change. These are hollow dowel pins. They go between the bell housing of the transmission and the engine block. Failure to have both dowels in place will lead to the flex plate cracking [see #2]
when installing transmission make sure dowel pins line up as move transmission toward engine,you have to raise engine slightly to make adjustment before bolts go back in transmission if transmission in a bind not align with engine transmission bolts will be harder to screw in place.
I don't have a very good description of what part you are working on, but sounds to me like you are either removing an engine or transmission and you are probably looking at a dowel pin. There are usually 2 in either the engine or transmission and they help to line everything up during reassembly.
alot of these get stuck due to rust on the dowel pins. If your SURE you have all bolts out then all you can do is pry it off.
Dowel pins are located at like 9 and 3.
it may be seized in the dowel pins. I run into this once in a while. There is a dowel pin on each side to align the engine block and the trans case. I heat the aluminum a bit to expand it and then, with careful prying and working it back and forth, it will come free. I like to clean up the holes with a file before putting back into the truck. :)
Please clarify which dowel pins you are looking for. There are dowel pins that align the head to the block, and dowel pins that align the transmission case to the engine block. I hope this helps you.
The engine should be separated from the trans at least 1 "and the torqu convert slid into the trans. There may be a dowel pin on each side. That is wh the one inc.
sometimes there are pins inside that are used for alignment purposes, try taking a RUBBER mallet and GENTLY tapping the seem, this can sometime help break any corrosion which may have built up over the years
look at your replacement transmission. straight thru holes are bolts on the trandmission side toward motor threaded are toward transmission. check each mounting hole and compare it to the trans in the car. if all are out it could be a dowel pin that is corroded. I have had to pry out transmissions off the dowel pins before. hopes this helps mike
