Is your kickdown switch properly installed and functional? See your Bentley shop manual for location and adjusting.

Are all hoses leak-free and attached?

Also , you need to get the brown bentley type 3 manual. Chances are 100% that you need to adjust the bands and also adjust the main hydraulic pressure through teh adjusting screw in the pressure modulator valve. Ray

brown bentley type 3 manual

now where can i get that from????????????? i only need to know about the gearbox? the rest of the car is compleat! and the engine is a 2.1wbx(140bhp).

p.s i wish i put my 091 in it now! then i could of put the turbo motor in it,now that would be fun!!!!!

That manual is awesome...even if your car is complete. It is the most complete (its factory) service manual. The automatic transmission section gives full assembly and adjusting info. I have found that about 10% of all type 003 automatic transmissions need to have the shift pressures adjusted from age alone.
Also...if you have over 7 years or 70K miles on one of these transmissions....it is immediately TIME to change teh seal and o-ring between the differential section and the automatic transfer case. Its not a matter of if...its a matter of WHEN...that seal gives out. It will destroy the tranny in MINUTES. Once the tranny is out of the car...its a matter of about 30-45 minutes to change the seals. Ray

In the manual....(I will look up teh shift points in my manual tonight)....you see a diagram of the small caps or covers on teh side of teh transmission. These are plugs that close openings in the hydraulic oil galleys. You need to pick the correct ones (there are only about six of which you might use two)...then screw in some steel tubing with the correct fittings. That could go a few feet and then have high pressure hose clamped on. You will need a gauge that feeds several hundred psi. You will need to have the gauges visible in the drivers seat. Youy will drive at several listed speed ranges and watch teh pressures at the shift points.
The adjustment to the pressure you are working with....will be done with a 4mm allen wrench...by pulling the vacuum hose off of the modulator valve and inserting the key through the vacuum tube....and turning one way or the other. I can get all of the specs from my bentley manual.....but you really should get this book. I would not own a type 3 without one. Its pretty simple...just need a few tools.

The engine must be properly tuned, valves adjusted, no vacuum leaks...and the bands adjusted...p[revious to starting this.

If it has just been rebuilt...its common to have bands not adjusted properly. Ray

thanks ray
the engine it perfect(i built it )
can you ajust the bands from the outside of the box???

[raygreenwood]

Yes! There are two or three set screws with locking Jamb nuts visible on the outside of the tranny. You simply (if memory serves) screw them in until they contact then either adjudt them to set torque or back them off a set amount of turns then lock down. I have not dug my brown book out yet...stay tuned. Ray

I believe those are on top of the tranny. Simply having those properly adjusted can make a big difference! BTDT
