The civic has +140000km,

When I start it cold and start running the car it does not present any defect , engages the right gear at the right time , the problem is that after a few km's rotated it creates a great difficulty to get out in first gear ( "D4" or "D3" ) , it does not climb uphill after this period.. then I have to engage the "2" because then he does not engage first gear and usually comes out on second gear . When I reach about 40km/h I put in D3 to enter the third and when I hit 60km/h I put D4 to get the fourth .

I bought it knowing this issue, not because they told me , but because I visualized this difficulty in testdrive , then thought about swapping to MT , but over time , I saw how useful it is to use an AT in everyday life ..

Well , now about 30000km with it as well , other defect is not engaging fourth gear sometimes, then I stop , hitch neutral and out again without any problems , and okay..

Researching this issue in the years, I came into some possible causes , but nothing that gives me the certainty of the defect .. among them are clogging the internal filter , a spring break internal valve transmission , defects in any 3 solenoids... i don't really know..

Trying to solve the problem, follow the honda bulletin 00-012 (in attachment), i flush the transmission 3 times (just change) and clean the tranny solenoids, but nothing..

Can someone help me with some information? Thanks

 

That TSB doesn't sound at all like your problem.

Stall test.
Test port pressure gauge tests.
