here I am back , after a lot of research and work on the box it is going much better ,it goes from 1 to 2 and 2 to 3 without problems , it remains a problem with the 4 , I have to climb to about 70 miles an hour for it to pass and it retrograde as it forces a little but well I don’t often need...

may be a track, in P,N,OD,D,2,1 the manometer acute is stable, in R, the acute shake , ca may be oriented towards the problem

my gearbox is a4ld , i hope she have not epc solenoid

yes the pressure is a little low , normally it is between 57 and 78 , reverse between 67 and 105 so at the upper limit , in addition when I put the reverse , the engine idle with speed increases , the speed is not regular , maybe the fluid is not yet at the right level

hi , I just took the pressures of the box , in slow motion , I have about 55 psi in P,N,OD,D,2,1 , that’s good in R I have about 105 psi , that’s a lot and it doesn’t back even by giving gazs , on the other hand it advances in D even in slow motion , an idea?

Hi guys , news from my box , it’s up but I still have a little problem , on reverse the reversing lights light up but I don’t have contact on P or N , someone has a trick to loosen the neutral switch without removing the gearbox?

the input shaft has two different length of splines , which goes into the box ?

when I put the torque converter back on the box, i have only 0.23 , Glacier indicates that the standard is between 0.375 and 0.625 , someone can tell me where the problem comes from? input shaft mounted upside down?

I noticed that during my previous reconstruction, I forgot to put washer back behind assy support, is it possible that this is the cause I didn’t have a third?

On the drum it is noted 7D047 , when doing a search on ebay it is written direct drum so it must be good , here is a photo with the number The o/d drum is the n° 7L669

on the second photo , the one with the holes , there is the number 7D044 the same number of the drum out , I think it is an update but I am not sure

I’m back, I took out the gearbox and it was the pump that dropped, so long as it was removed I took the opportunity to see why it didn’t pass in 3 , I realized that the two drums were the same , with hole , my old box had one with hole and one without hole , see pictures , is this normal?

good I have to think, I am not equipped to remove and put back a box, no lift and no pit

good , pressure test gives 0 , pull the chiller line no oil circulation so the pump is the problem , you have to pull the box completely to replace it or is it possible under the vehicle?

I think it’s misunderstood, the valve I cleaned is the one in the red circle

7000 rpm could cause overpressure and tear the seal of the vb?

small test today , the level drops with the engine running so the pump always goes , when I put in reverse or before , the engine speed changes but no thrust , and we hear a slight friction , an idea?

I wanted to check the throttle valve and I put it back wrong , the accelerator was fully open , when I started it went up to 7000 rpm direct , it only lasted a second but I think it was enough to break something in the box

Aiiie , the it’s dead , starting the engine , the accelerator petal was set and the engine mounted 1 second at 7000 rpm , too late now I no longer have any speed either front or rear , believe that it’s screwed for good

I don’t know if I can solve my problem but I thank all those who try to help me for their patience in trying to help the people who need it

yes I understand , the gear could turn in one direction and not in the other for example

No one knows how to answer ?

Would it be possible for the hight/rev clutch to run in the rear and not in the third?

ok I want to believe you and thank you again for trying to help me but if it is not the tcc , I do not see what the problem is

here the summary table in english

the tcc is applied by the solenoid tcc , I tested it in oms and it is good but how do I know if the ecc iv sends the signal?

in this picture you can see that the tcc is active in d 3 an D 3 an 4 , the tcc in french called : embrayage de blocage de convertisseur de couple

i try to translate the french manual Selector in position D (3 direct take ratio ) The torque converter lock clutch is applied and thus provides a direct transmission between the turbine and the pump. The central shaft is connected with the uni-directional clutch O/D with the input shaft and...

ok there was fluid missing , now I have 1 and 2 and reverse that are going great , but the gauge says too high , and still no 3 it comes back in 1 , so I noticed that will not pass in 2 if I am on D or OD , still the same problems , the only thing that is activated in 3 and not in 1 or 2 it’s...

News from my box , I removed the VB and all cleaning , valve by valve , no dirt in sight , all reset by tightening the plate to 9.5 nm and the rear servo to 11 nm , new filter with extension , an external filter in addition to the output of the cooler , cleaning the valve of the vaccum , put...

of course we can buy the same but if we have two old sockets we are saved ;-)

here in Belgium it does not often freeze very strong , and when it freezes , I do not take the Bronco so it is not a problem for the return to the box , I know the hose to which I must connect

yes I can do this , however I have planned to add a temperature gauge on the transmission , the probe is already in the pressure test port

ok I will try to do this this we , cleaning of the pipes , vb of everything possible , adding an external filter that I have to receive tomorrow and we will see if there is a difference

the transmission was clean , the oil was new , I haven’t done 50 miles since it came up so this mud can only come from pipes and radiators , if mud went directly into the box it could block a valve , the pipes and the external radiator no problem to clean them, but the part on the side of the...

Thanks Transman , the problem is the part that holds the main cooler , I think we can not get around it , it serves to cool but also to heat the oil or I’m wrong ?

I don’t think it’s the clutches that are worn out , they are new , on the other hand there were a lot in the old box and I think there are a lot left in the pipes and coolers , I may not know how to clean them

I recommend filters with an external one, when I have them back, I will pull the body valve to clean it, I pull the housing 6 or 7 times and each time, there was a black mud around the small magnets I put in it, maybe some mud sticks a valve, on the other hand I do not know how to clean the...

I think the level is good now but I will watch it , I come back to Sonnax answer ,the direct clutch is used by the reverse gear, and the reverse gear works well, the direct clutch may not work forward?

Hello, yesterday I wanted to take a little ride with the B2 , when I came back to the garage I came up with the idea of rechecking the oil level , and nothing on the gauge? , I put back some oil, I’m going to go around again , same thing , I did it five times and put back about 4 quartz before...
