I apologize ahead of time if this isn't the correct place to post this I am new.
I recently replaced the E4OD transmission in my truck as well as the torque converter along with the vss mmlps and tps sensors I now have a slight grinding noise from around the area of the bell housing of the transmission and back of engine it is quite audible but is only within a certain rpm rand and tthe engine runs allitle ruff in that rpm range as well I am at a dead end as far as what to do to finnd what is the issue and how to fix it any help would be greatly appreciated!
