Hello to all

hope someone can advise or give a opinion. I’m in the process of motor swapping my 5.3 a lil back story I picked up this rig that needed a motor. Motors out currently souring a new used one.

I'm currently cleaning the engine bay and cleaning up the harness also fixing anything that may need replacing while the engine is out. I noticed on the torque converter it has a date of 7/2017 stamped on it and looks relatively newish.
could one speculate that the trans was rebuilt or swapped out at some point? Rig has just over 200k on the dash and PO purchased in 2018 but had no knowledge of the trans being replaced just knew it was very smooth and had no issues.
How can I find out if the trans or just the torque converter was replaced? Fluid looks great solid red not dark and has no burn smell to it.
any suggestions would be great. Thanks

 

I really can't think of any way a vehicle manufactured in 2008 could have anything with a 2017 date unless something was replaced..

If all works fine, sometimes best to leave it alone.
