No particular recommendation just a comment that the 5-45RFE transmission is and has been in a bunch of DCJ vehicles for like a decade along with mods including beefed up TCs and kits like the transgo so any decent transmission shop that has done work on this transmission should be able to do the job (i.e. it's not a CRD specific thing). I know my local DCJ dealer has installed several SunCoasts TC in Dodge trucks for example.
