Im replacing my 4r70w for a TKO and thought it would be a great time replacing the wiring system and the heater box. So I went for this, small unit that will fit my needs. The wiring harness is from American autowire highway 15 plus. More pics will come, the old dinosaure heater box is now history
Just following up on this install.... wondering how it went and what had to be done to get this in.... any downsides.... do the vent levers still work?
Thanks!
