Transmission fluid flush vs fluid replacement
Scotty I love you’re Utube channel.
I have a 2017 Ford Transit 3500HD chassis under my RV. It has 58,800 miles on it. 99% are highway miles. We use it for travel not camping. It has a 3.7 liter v 6 and an automatic transmission.
I asked my local firs truck shop to replace the fluid and change the filter. They said it would be a 3 hour job just to remove the subframe and then split the tranny to drain the fluid and change the filter. They want to flush the fluid in the tranny. Should I let them?
thank you Chuck
Should I let them?
No. And stay away from these external flush machines. Instead opt for a fluid replacement. A Transit's transmission fluid can be changed without "power flushing". Chuck's right, take it somewhere else.
They said this tranny does not have a pump in it, it works just by the mechanics of the unit.
Automatic transmissions work with hydraulic pressure and will have at least one pump to develop that pressure. Some have both a front and a back pump. Take that thing to a mechanic who has some idea of how automatic transmissions work.
