SHIFT TRANSMISSION FORD V-10

Recommended Posts

I have had various campers ask me about shift patterns for Ford v-10

The attached file will show what a Ford Engineer sent me shifts on SPEED.

This attachment explain speed to MPH and transmission gears. You will see

why the Ford v-10 will rev out to about 5000 RPM in 3rd, 4th, gear.

Its scary when this happens, but the engineer explain to me this is by design.

This happens when pulling a up hill climb grade's. 

At 60 MPH cruise at 2400 RPM  .

We had a 1999 31' Winnebago Class C and the engine was designed to rev to get the power.  So let it rev up on the hills.

Tim, not shure what your problem is? Many have gone to a 5 Star tuner to help refine the Ford shift points. https://5startuning.com/

The Ford V10 is designed to reve, I don't think you can hurt one if you drove it flat out as it has a built in rev limiter.

That doesn't sound right to me.  My Previous coach was a 2001 and I believe it was more around 2000 RPM.  With the advent of the 6 speed transmission, it has to be lower?

I know my newer 2010 on the Workhorse chassis is at about 2000 RPM at 70...

Be aware that that engine was used with a number of rear axle ratios and tire sizes, so there will be no "here is their RPM at a given speed for all applications".

Good points Brett! 

One also has to remember if the transmissions are setup with 4, 5 or 6 speed transmissions. There can also be different Torque converters, they can very slightly - dependent on the chassis wheelbase, that changes total weight of a coach and then add a towed. 

The Tow / Haul switch being on or off directly affects shift points and how the engine / transmissions shift and breaking works.

One size does not fit all.

The chart is for the newer 6 speed transmission, which was introduced in the E-350 & E-450 chassis in I believe 2016.  The F series (truck chassis) got the 6 speed earlier.

However it looks like the F-53 chassis still only has the old 5 speed, even in the 2018 chassis. 

The F-53 is used in Class A and the E-350 & E-450 us used in the Class C.

This from the 2016 F53 Owners Manual:

 

The transmission code is on the Safety Compliance Certification Label. The following table shows the transmission code along with the transmission description.

 

Description  Code 
Six Speed Automatic Transmission (6R140)

Brett,

I was concern that I was giving out good information, SO, I called

my Ford Dealer this morning. We ran my VIN and we find out the transmission

is a "5R110W" a 5 speed. Engineering ford sent me the form for a 6 speed.

But, all the same the transmission still shifts on SPEED.

Thanks, for helping  bring light to all of this. The motor home started as a van E-450 2013.
