Hello, I have a 2003 Honda civic es1 model does uses the myla transmission. The car had to warm up Before it could move and one day the customer force the car to move as it wasn't fully warmed and then it stopped moving. The transmission was rebuilt with new seals and valve body serviced , and I am using valvoline multivehixle transmission oil. The car moves when up on jack stands but crawls when I placed it on the ground and give it gas. I know these cars uses honda dw1 fluid so I wondering if this can be the problem? As I am having a hydraulic pressure issue? The car has a d15b engine
Scotty does not generally return to topics he has already answered.
no it wasn't replaced.
Probably the torque converter should have been replaced as a routine matter during the rebuild. The thing is 23 years old after all. Who rebuilt the transmission? A remanufacturing facility? A corner garage?
How thorough was the rebuild? You stated that seals were replaced and the valve body "serviced". Were friction surfaces replaced? Any hard parts replaced? (Or, if it is a CVT, was the chain replaced?)
Obviously the freshly rebuilt transmission is not working properly. Does it have a warranty?
We don't have a pressure test kit,
Get one. If you're going to work on automatic transmissions that is one of the most basic tools you need for test purposes.
I was thinking the other method of checking if there is good pressure by removing the hose that pumps fluid to the radiator
That won't work. The hydraulic pressure has to be correct, you can't check that visually by how it's coming out of the cooling lines. (Though you'd see if there were no pressure at all.) Get a pressure gauge.
would that help determine if the converter is working?
No.
Another problem is you used the wrong fluid. Why did you do that? Hondas are very picky about fluids. A "multi-vehicle" fluid is not really right for anything.
Well it's very hard to rebuild those things. It may not have been done correctly. You do need to use the correct fluid of course. But also realize it could have a bad torque converter which would do the same thing. Was the torque converter replaced?
@scottykilmer no it wasn't replaced. We don't have a pressure test kit, so I was thinking the other method of checking if there is good pressure by removing the hose that pumps fluid to the radiator , would that help determine if the converter is working?
