Frequently Asked Questions
With a TH-700R4 transmission installed in place of a TH-350 or TH-400, what can be expected as a reasonable mileage increase?
your engine RPM drops from say 3000 RPM to approximately
2000 RPM you will typically start driving at a higher average
rate of speed on the highway because it will seem so natural
to do so. If you choose to cruise 10 to 15 miles per hour
faster on the highway than you did before the transmission
upgrade, you probably won't see the dramatic increase in
fuel economy number, but you certainly will get from Point
A to Point B a lot quicker, smoother and quieter! One thing
is certain, when our customers have given us feed back,
they invariably state they are getting "very noticeable"
improvements in Mileage.
