of course its very insane, and the rebuilders wanted 20,000 MXN and they arent very reputable people so i started the rebuild process by myself, beleiveme that if i should received a cost of 1600USD i should asked for a discount becuads i shouldnt need the intallation, and also it should be very less problematic that all the things i am passing.


and well, now returning to the old windstar, i have changed all the valve body for a rebuilded one with new sensors and pumo.


the problem is now more strange i am thinking in a internal leak of oil, i dont know where, but ther are two posibilities, on the N-D acummulator or the intermedium band servo, also it could be a piston of the clutch packages, but i dont think so because there are all new.


i am almost sure that its a leak in the N-D servo because when it fails it provocate a hard shifting into reverse or low, the low makes the hard shifting in anyway, i mean if you select 1 or you select D it makes the hard shifting, at least that says wikipedia, and the logic makes me think that if that has a leak, the generated pressure should be inssuficient for applying that gears.


well i tested out in the highway, or freeway i dont know how is the correct translation, and well it feels very very well, the upshifts were so smootly almost unfeelables, also the downshits for accelerating, there were a little retarded but it was very well, so because the fixing needs to remove AGAIN all the tranny i will left it in that status untik the next vacations period.



many thanks to all for your helpfull


i will try to apport things to the windstar subforum.
