Keith in CO said:Hey Darius,
The TH400 in my 500cid 4x4 is dying a slow death, and I am trying to figure out whether to put $$ into a rebuild or into a 4L80e. I would love to have the OD (so I can put lower axle gears in), but I do not want to spend $1k on aftermarket electonic controllers plus the cost of buying the 4L80e, so I am still wanting to find out if anyone has actually made a JY diesel controller work behind the Caddy gasser.
BTW: Since my 429Cad/TH400 switchpitch Stude pick up street rod has been sitting in my garage for over a year untouched, I am planning to put it up on epay, and move on to other projects.
Are you saying that if I put a 4l80 behind my 472 the overdrive wont kick in till around 70? If so then thats perfect because 75 is the average cruising speed on the highway these daysturbo 400 is where he got better millage -maximum torque specialties forumn is where i seen it-cruz rpms is where your going to get millage,i tend to believe it,thou i like the idea of overdrive but not with a cad-hell your allready going seventy
No, that might be the case at full WOT, but depending on gearing it would be preferred at moderate cruising acceleration and around town to shift to 4th around 2200 RPM. In my truck thats about 40.Are you saying that if I put a 4l80 behind my 472 the overdrive wont kick in till around 70?
