What was the first year for the switch from 2v-V10 to the 3V with the 5R200?

I'm looking to buy a used Motorhome and want the new transmission.

 

I don't know of a 5R200 transmission but in model year 2005 the V10 in The Super Duty (F250, F350, F450, F550) line was changed over to 3V heads and coupled with 5R100 TorqShift.

I don't know when the F53 chassis (Class A) got the 3V engines and TorqShift but it may have been the same year. I know even less about the van based (cut-a-way) chassis. I don't think that chassis ever got the 3V but may have gotten the TorqShift. I know very little about that line so hopefully someone can give you solid info.

 

I don't know of a 5R200 nor a 5R100 transmission. Ford never offered a transmission with either of those names.

In the F-Series, including the F53 motorhome chassis, the switch from 2V to 3V and from the 4R100 to the 5R110 TorqShift transmission occurred in 2005. You have to be very careful with motorhomes, though. RV manufacturers often buy a batch of chassis and take some time to use them up. It is not unusual for a 2005 motorhome to be built on a 2004 chassis.

The E-Series (Class C motorhomes) never switched to the 3V engine, but they did switch to the 5R110 TorqShift transmission in 2005.

 

Mark, I was told the 3 digit number at the end of the transmission model name relates to it's design strength....just add a zero. So, the 4R100 is designed to handle 1000 ft lbs of torque and the 5R110 is designed for 1100 ft lbs. Is this correct?

(Sorry for the ).

 

Whoops! I missed a digit when I typed. Should have proof read.

 

The higher the number, the stronger the transmission, but I don't think "4R100" means the transmission can handle 1000 ft. lbs.

Ask anyone who has ever owned a 4R70W transmission. It could not handle 700 ft lbs, or even half of that.

 

Yes, that's correct. BUT - that torque rating is AFTER the torque converter multiplies engine torque. Most converters have a 2:1 conversion ratio, so a 1000 lb-ft transmission can theoretically handle a 500 lb-ft engine.

The 5R110 was mated to a 570 lb-ft engine. The converter had a multiplication factor of 1.9:1. The maximum engine torque occurred at an RPM that was higher than stall torque so that the maximum torque was never available at maximum torque multiplication. So the trans at the input shaft never saw over 1100 lb-ft.

And yes, the 4R70W is rated for 700 lb-ft AFTER the torque converter multiplication.

 

Thank you for the validation and clarification. Makes perfect sense.
