Attached is a link to the 2/4TEC Trane convertible air handler data guide.

While perusing the information for the 5 ton version, all the data is exactly the same for both the R22 and R410 version, even the TXV valve. The only difference I could see was the low side pressure line size was reduced.

Does this make sense?

The expansion valve is different as well. The 2TEC would have an R22 valve, the 4TEC would have a R410a valve.
