Ford 600/800 series SOS no reverse

Rebob#1 · Sep 5, 2020

Having a problem posting since I changed my Email address. Rcd. notification earlier that all OK. Then notified
problem still exists. If this post goes through jump right in with words of advice. In following IT shop manual
best I know how, I dont have R2, R1, Nuetral on my later 63 or 64 SOS trans. Tractor wants to propell forward.PP 84
says in regard to # 5 selector posn. "if servo 3 reading is higher than servo 2, it would indicate a leakage @
servo #2 Then on PP 88 The chart shows #5 posn. Servo 2 = 0 psi, and servo 3 180 psi.. which is what I have! This
book implies this is a check on system pressure relief valve. I have taken all pressure readings on 3 servos but
ar'nt able to diagnose. Rebob#1

first off. 600/800 series were not available w/SOS.

Secondly, What do 9th and 10th do? There are no fail scenarios in the SOS that do no involve at least 4 ratios that provide propulsion.

Yes Larry, I should have used 601/801 in subject. I have some problems with the selector binding up in #9 and 10
that I havent resolved. #1 servo 0 psi in pos. #9, #2 servo 0 psi pos. #9, #3 servo binding selector no reading as
of yet. The tractor is a morphodite with about 3 different tractors, sheetmetal combined.I consider it a 801 series
with 4000 decals.AQ 1964 SOS.Serial Numbers ground off! Just what pressure should I be looking at in pos 9 and 10?
What do you see wrong in my earlier post in regards to pressure @ posn.#5? As long as I have your attention I'll
ask the question of SOS on my earlier post, When the cams on rack are in non activated state, the plungers
extended, rockers even, Park switch depressed. Unsure of control valve as I dont want to mess with it. I considered
it the point to set lower selector cable @ 2 3/4 in. per IT FO-20 Am I correct? Thanks Rebob#1

(quoted from post at 11:30:37 09/06/20) I have some problems with the selector binding up in #9 and 10
that I havent resolved.

So, in other words you can't tell me how it acts in 9 or 10? Guessing it doesn't leading to suspicion of a C1 failure to apply condition.

#1 servo 0 psi in pos. #9, #2 servo 0 psi pos. #9, #3 servo binding selector no reading as
of yet.

provided this is a blue transmission (DDC)B1 is correct. B2 should be at 180 +/-10. B3 should be same as B2

What do you see wrong in my earlier post in regards to pressure @ posn.#5?

Nothing at all.

As long as I have your attention I'll
ask the question of SOS on my earlier post, When the cams on rack are in non activated state, the plungers
extended, rockers even, Park switch depressed. Unsure of control valve as I dont want to mess with it. I considered
it the point to set lower selector cable @ 2 3/4 in. per IT FO-20 Am I correct? Thanks Rebob#1

I don't use IT. But that is a starting point. You may need to fine tune it to your unit to get selector positions in agreement with transmission positions.

(reply to post at 10:33:04 09/06/20) qLarry Back again, The xmission is a C3nn-7006-B In 9th posn. there is no movement! Awaiting # 10 posn. repair, also have removed the lubrication pressure switch near traction coupling due to broken wiring, a terrible job!. I will probably need to wait for re-installation before I start the tractor. In #9 posn.#1 and 2 servos have 0 psi, the manual as you state calls for 180 psi for #2&3 servo I will recheck also. At this point I do not have good understanding of the chart FO173 In the TI manual,for how to interpret. need help. Thank you sir. Rebob #1

Just a follow up on earlier post- I found my problem is in selector, pressure check on servos fine. All 14
positions OK, Thanks to all Rebob#1
