My TCM Went out on my 09 ISF that part is now discontinued 89535-53040, Will i be able to swap another year ISF TCM in i don’t know if they are superseded part they other tcm’s have the same part code and same part number just 2 digit’s different at the end. The Engine control module’s on the other hand are supersession’s I look at lexus parts now and it says “Replaced by” but it doesn’t say it for the TCM only the ECU For example if i swap a 2010 TCM into my 2009 ISF will it work? or will i need a 2010 ECU and a 2010 TCM to make it all work. Its all very confusing. Are all ISF’s pretty identical in terms of harness’s and hopefully this will be plug and play

Thank you
