4000 transmission fluid level

[Pappa J.]

I just got a 74 Ford 4000 with an aftermarket front end loader on it (that has some minor leaks). My understanding is that the transmission, rear end and hydraulics all run on the same fluid, is that true?
I don't see any place to check the level, I looked on the sides for a level plug, where do I check the fluid level and what kind of fluid do I run in it? thanks PJ

Aloha Papa J I just repaired the IPTO which is located under the seat. We had to split the tractor between the trans and rear end. We found a plug located on the hydraulic pump face on the right side of the tractor just below the seat. The trans has a square plug located on the right side of the trans inline with the foot rest. The trans takes 90w oil and rear end and under the seat assembly is one cavity takes valvoline ( I forgot the number) will get it to you tomorrow. Good Luck Mike

Yes... the 4000 runs 134D or it's equivelant in the transmission and hydraulic/rear axle sections. They are two separate sumps so yo must check both, but they do use the same oil.
You could run 80W90 in the transmission but that generally makes them hard to shift. 134D was the original recomended oil.
It seems to me that there is a level plug on the right side of the transmission about half way up and the fill is on top.
The hydraulics are checked at the level plug around the pump housing, just by your right heel. The filler is behind the seat, I think on the right...

What year did they go to common sump.. my 75 5000 doesn't have the trans level plug..it's just a flat boss that was never drilled.. pouring oil into the rear fill makes oil come out the trans drain.

all I got is the rear axle trumpet level plug.

is this a late 75 deal only? I know the earlier year models ones had a seperate tras sump.. but never have heard of when the cutoff was? You or rick know the cutoff year?

I don't think the 4000 ever went to a common sump. My 1979 4600 is not common sump but my 1980 5600 is common sump. The 5600 has a dipstick on the left side under the seat while the 4600 has a dipstick for the tranny and the plug for the rear end hyd fluid. It has never really made sense to me. I would think that for what it cost, adding a dipstick to every sump made sense.

3 bangers were separate right until the bitter, bitter end in the late 90's.

I think the 5000 8 speed was in 75 somewhere but the dual power models would have been common right from the start... in 72 or wherever that was. I'm not up on the specific dates of those things with the 5000. Rick or Bern would probably know more accurately than me.

I thought all 5000's (and all 4 cylinder Thousand Series and newer) were common sump after Dual Power became available. Bern has corrected me and says any 4 cylinder 5000 or 5600 less Dual Power will have separate sumps. Dual Power became available 6/1/73 according to the parts catalogs. For sure any 4 cylinder Ford with Dual Power is a common sump machine.

Aloha Papa J Just got in from the ranch. I have been using Napa Valvoline 710 which I was told by the parts people is the equivelent of 134D. If I am wrong some out there please correct me. As to the trans Rod is probably correct. Mahalo Mike

Hmmmmmmmm.
I was just thinking about this now.

Sounder says his is a 5000, 8 speed with a common sump if my memory serves me?
I'm also pretty sure it's got the rotary pump...

Wonder if it's not a 5600 that had it's clothes changed and a gen put on it?

Sounder, did you run the model, serial and unit codes to see what it is?

Thank you, excellent information from all. Is there any kind of trans or hydraulic filter I need to clean anywhere?
