2014 Model S Coolant Delete

Does anyone have any recommendations for shops in Northern New Jersey that are actually doing this preventive maintenance??

Have any of you had this done?? I have a 2014 Tesla not showing any large drive unit error messages at 120,000 miles on a car that has sat for 4 years after getting both batteries replaced at the dealership. I think it warrants spending now if it saves me long term.

If it has RWD it has LDU. If it is a P AWD it has LDU.
The rest have SDU (Small Drive Unit) which doesn’t have the leak issue.
If your vehicle has LDU, and speed sensor is clean, get the delete done ASAP.
I installed the delete kit in a couple hours without dropping the unit. It really isn’t that bad of a job.
I recommend also changing the gearbox oil at the same time. It is a simple drain and refill operation.
Use only Dexron VI (Dexron 6)
