i have a 91 with an auto without overdrive. are these trannies pretty stout? my plans are to put a 3 speed brownlipe behind it 20%under, direct, 20%over. and already installed the 4.10 dually rearend. is the tranny going to hold up to a lot of pulling and if not what do i need to do to it to tote the load. i regularly haul 10 tons not counting trailer.

 

IMO i dont think these trannys are very stout at all. i believe a non OD is stronger as the OD unit is a weak link. but the torque converter and valve body are the notorious weak links. but if your hauling 10 tons regularly i wouldnt trust the 727 but thats just MY opinion.

 

im planning an nv4500 swap but idk when i'll have the time. i have anv4500 chevy tranny. do you know what itd take to put it in the dodge

 

alot. new hydraulics, adapter plate, starter. clutch hydraulics, clutch etc. unless you pay the bucks for one of the adapter bellhousings

 

i have the hdraulics, starter, bell housing, and clutch. will the nv4500 bolt up to the first gen adapter plate. if not i have a 2nd gen. adapter plate

 

if its a chevy bellhousing then no it wont work. if its an nv4500 dodge bellhousing youll need a 2nd gen adapter plate

 

Hauling 10 tons regular I would not truck any light truck tranny for very long.

With a few modifications the 727 in the 1st gens is a VERY stout tranny as far as autos go. The converter is alot better then the 518 converter but still could use a upgrade.

 

i have a dodge bell housing. idk. i prolly start gathering what i need and when i trash the auto, i'll swap in the nv4500.
