89c3500dually
Newbie
I've searched the interweb up and down and can't find a concrete video or all helpful DIY forum answer so hopefully one of you fine folks can help me out. I have an 89 c3500 dually that I would like to put either a 4l60e or 4l80e trans into as I would like overdrive and better towing capability. Has anyone here done it and if you did please help me out with some questions such as.
1. Which is better 4l60e or 4l80e?
2. What standalone ecu did you use?
3. Did you need an adapter plate?
4. Did your engine need any additional add ons to work with the trans?
5. What harness did you use or did the factory work?
Any insight is greatly appreciated as I would like to undertake this very soon but would like to have all my ducks in a row before I start. Thanks in advance.
