Howdy, over the winter I swapped my "64 poly d~100 420 to a 435. Had it gone thru/ rebuilt by a tranny shop, and the 3~4 shift is awful!! Seems to be sticking in 3rd gear!?! 1st 2nd 4th and reverse seem fine but does not want to come out of third. It slides in ok and when I let out the clutch in 3rd...

make sure all the oil galley plugs are in the block... my machine shop left one out and I had no oil to either rocker bank on my 318 poly...

Howdy, just throwing this out there in case it can help someone down the line... I am in the middle of swapping my 420 to a 435 with the parking brake on the trans. I believe the 435 is out of a 1965 D~100 and there are a few differences that I was not expecting. Overall the 435 is roughly 1" longer...

Howdy, I'm no Holley expert so don't listen to me... I would start with a vacuum gauge and hope to see 17~20 "inches of vacuume". The four corner idle circuits are then adjusted for max vaccume and highest idle RPM. your vaccume @ idle dictates your power valve size... vaccume number divided by 2 is...

so I got a little more info, the tranny I found is out of a 1 1/2 ton 65 d~400 so I am assuming it has the larger input shaft and uj yokes. Wondering the cutoff for the smaller input shaft did they beef it up @ 1~ton? part number is C-96041

Thx d

Howdy I am attempting to replace my stock NP 420 in my '64 d~100 318 poly with a NP 435. Question: will one out of a larger truck d~300 ~ d500 work? direct bolt in... I have sourced one from a junkyard, but don't want to get stung on a little detail like wrong u joint size or something and have 200#...

Howdy, Just getting my fresh built 318 poly broke in around 500 miles and a problem has developed where my NP 420 manual trans {fresh rebuild} will pop out of 2nd {never use granny 1st } gear on its own. Seems normal under a load {throttle down}, but when you let off the gas it pops out of gear. Any...
