so, I just bought fourbyken's M1008 and so far so good, except I'm NOT digg'n the 55mph top speed. As such i wana do an overdrive mod to the vehicle. SO.... what's the BEST way to do this without breaking the bank? I'm lean'n towards a 4l80e cause I like the idea of an automatic in a pick up BUT I see the compushift ECM is $1200 alone THEN i'd need to find a DECENT 4l80e, THEN have it all installed!!! so it's look'n like it's a $3k swap by the time yer all said & done??? I'm NOT going to put a 700r4 in it, NOBODY says it'll hold up, the Gear Vendors seems even WORSE of an idea as it costs like $2500 and ONLY works for ya in 2wd AND always has the torque converter working overtime... SO, what's yer best suggestion??? What am I look'n at to do a NV4500 manual swap? ...bout the same $$ wise as a 4l80e all said & done, or way cheaper?? I'm at a bit of a loss... lil help would be a HUGE step down the right path! thx guys!!!
