The 47RH was used up until the 1995 model year and the 1996 to 2002 trucks have the 47RE. You really need to rethink your tranny guy's abilities.....

Thanks Tom, I knew the 12V had switched to the RE before the 24v came along just didn't know the year of the switch.

You're welcome, Bill. My truck is an early '96 and it is the first year of the REs. My 'problem' with it is the software to run it. A lock up switch won't work on mine unless I get the PCM reflashed..........

Talked to the specialist and mentioned they're almost the same ,should I ask him to set up the lock up switch?For sure I'll hook up a temp sensor what is the best set up for the temp sensor

I had heard that before, but not any first hand knowledge. Defineately do the lock up. If you ever put an exhaust brake on you will need it.

Here are the directions for installing a lockup switch: http://www.tstproducts.com/Torque%20Converter%20Lockup%20Switch.pdfFor a temp sensor you could use this: http://www.genosgarage.com/prodinfo.asp?number=ACUTEMP_ADAPTER but in my opinion you should use the hot line out of the transmission like this one: http://www.carid.com/dorman/fixed-auto-trans-oil-cooler-hose-assembly-mpn-624-352.html?gclid=CMvb4KbYycMCFYgAaQodvxgAvg

Chech the linkage on the tranny, driver's side. If there are cables and metal brackets it's a 47re, if there's a big plastic box it's a 48re. Behind the bell housing and over the tranny pan.

The early 48RE's used a TV cable just like the 47RE. In '04.5, they started using the TTVA on the 48RE.
