Re: FORD T18 or NP435 Hunting
My NP 435 is out of an 86 Ford F150 they were also used in the F 250 vehicles as well. the top is Aluminum reverse is over to the right and down,there is a longer throw going into 1St gear. First and reverse are non synchronized.I have read about a fifth gear option ,by replacing the 3-4 synchro.with a gear but never checked into it any further.
I understand the aluminum bearing cap for the countershaft is difficult to find so be careful if you go to replace that bearing ...I cut mine out .all the bearings were obtained from a bearing supply place.the Thrust bearings were the most difficult to locate.
Ford didn't build any of those transmissions they sourced them out and used what was avalible /cheaper at the time.
