Its a bit of a long story but thought I would touch in with some of the people on this form who may have advice on a DIY transmission replacement in a 2017 Lincoln MKZ hybrid. I purchased this car and wrecked condition with a salvage title. The damage was minimal. No frame damage. Just sheet-metal and headlights. One thing that did go unnoticed however was crack in a transmission cooler line right where it enters the transmission. The crack was so minor it was not noticed for about 500 miles before it bleed itself dry. Even with basically no fluid the car ran and drove fine but made a very nasty scrapie Whirley sound. Upon discovering the problem I replaced the lines and put new fluid in and the sound volume decreased by 50% however the whirling sounds are still so aggressive I am quite confident the bearings are toast. The car actually runs and drives fine even while making all of the sounds. This car is something we are going to use as a family cruiser so I know I need to fix it soon. My first question is what are the risks of driving it in this condition to doing any further damage to anything else? I already have a replacement transmission from a wrecking yard and plan to make the swap over the next few weeks. Ive had years of repairing and restoring cars but this is my first electric. I am looking for anyone who has service instructions on replacing the transmission that could be shared? Or real world first hand experience in replacing the transmission. Im also interested in learning from anyone who has used a android scan tool to be able to interface with the obd2 functionality related to transmission operations, temperatures, etc.
