well while we are on the subject, do yall also have to wait a fairly long time to be able to shift from first to second? I am almost certain i have the NP435 with granny first. i usually start off in 2nd, but i thought this might have been causing unnecesary wear on the clutch. it just seems like it takes forever to wind out in first. it isnt a big deal. it doesnt seem to be a problem, but it would be usefull to use first in the city.

IDIOT!
I was starting to get some clutch chatter along with the hard down shifting so I dropped the tranny today to swap in a new clutch and rebuilt NP435/NP205. Upon removing the tunnel cover I discovered the iron top.
T18!
I swear I had taken a good look from the bottom before and verified the aluminum top. In my defense I have never seen so much oil on a transmission or transfer case. What a greasy mess all over me, the truck and the driveway.
I Didn't find my clutch chatter. It all looked new with the exception of some marks on the flywheel surface. Was too dark to see exactly what it was.
Friday I made the extra effort to get a flywheel from a junk yard. I took it to the machine shop for surfacing and a new ring gear so I could complete the swap this weekend. When I went to pick it up the machinist had broken it! He tracked down another and was to have it ready this morning, he broke that one too.

The 3-4 synchro is going out on my t-19 and I'm thinking about going to an np-435 so I can have a deeper 1st gear for crawling up and down hills when I'm out four wheeling. Ford put np-435's behind 460's right?

My tranny shift alright, I mean... you do have to work with it. But my only problem is sometimes when I'm in 1st gear or Reverse... it likes to pop out of gear. This happens once in a life time with 1st, but with reverse... its so common that I've gotten used to just holding it in place. Whats wrong here? Just linkage or what? I dont know trannys at all.
Its Comin Right for us!

holding my 435 in reverse while pulling a truck backwards up a hill at 5k rpm is what blew mine up....likely you can fix it by putting a shim on the detent ball springs for 1st and reverse...maybe pull the rail and grind the groove a bit deeper if that doesnt work
