Ok, still up in the air about the trans I wanna throw behind the new engine.
Options are, 4L60E, 4L80E, TH400, or TH400/GV combo
Option 1: 4L60E costs $2925 with a 2 year warranty, and would require just a reflash of current converter. Downside is, google fast cars with 4L60Es and, you do not see many, if any at all. They are not meant to be raced and this is a factor in my choice. Upside is, it would obviously bolt right up and require no mods.
Option 2: 4L80E costs $2200 for a 1 year warranty, and would require a trans crossmember at $170 and a new converter at $845. OR, a full "kit" which covers all the stuff I need to swap it in for $3500 and also gives a 2 year warranty. The trans can handle more than I plan on throwing at it, and comes standard with a T brake, BUT, will require cutting/BFH mod to the trans tunnel.
Option 3: TH400 costs $2500 with no warranty(local used unit) but would come with everything I need to bolt in and go. Converter would need to be restalled. Upside it would also handle anything I throw at it but, I lose OD and lock up.
Option 4: TH400 with GV unit, not really a practical option as it would cost well over 5k to and I could easily just do a 4L80E for less.
So, at this point I am wondering how much value I place in lock up and OD in the trans. Granted cars came with 3 speed transmissions well before this so it can be done, just curious how people would feel in this situation given the options.
