 The 4t80e was rated for 305 ft-lbs of torque, though some have estimated that it may be strong enough to handle 600 ft-lbs in stock form.
+It is far stronger than a 4t65e even in stock form and can be upgraded for much cheaper than a 4t65e.

 ===== How to make it work =====

 The rear knock sensor on the 3800 will need to be removed to make room for the transmission\\
-The rear lower bellhousing bolt will need to be grinded a little bit as well.

-Some of the bolt holes do not line up, and you will need to make a bracket to support the tailhousing
+The rear exhaust manifold seems to interfere with the transmission as well. You may lose some clearance for the downpipe since the transmission is so big.

 The flywheel will need to be drilled since the torque converter uses 4 bolts instead of 3. Spacers may also be a good idea.\\

 ==== Electronics ====
-The
+The stock 3800 pcm is capable of controlling the 4t80e just fine with some tuning work, however you may need to do some homework here. \\ You could also use your own electronic switches to trigger the shift solenoids manually for manually controlled shifts. You will need to make sure the shift pressure is set properly though manually since the PCM won't be controlling it in that situation.
