Do automatic transmission lines have pressure when in natural at idle..
mine leaks when i move it but when sitting still at idle i cant see it drip..i have read on the internet that they are common to leak where the two lines meet together

1984 Volvo 240 DL

 

The fluid is circulating at idle in Neutral, so it is under some pressure. And no, not "common" to leak, and what do you mean "where they meet together". Doesn't really matter, I guess you have a leak that needs to be fixed. Are you trying to pinpoint where the leak is?

 

yes sir i see where it is wet where the trans meets the engine and just below that to the passenger side the trans lines are bolted to the frame by a clip that keeps them together .. if i start the car and let it idle it don't leak but if i put it in gear and move it forward a little it will leave a little puddle of fluid on the ground..the part that holds the trans lines to the frame is wet too

 

 

OK, where they come together is just a bracket, unlikely to be leaking from there. You do have a leak alright; looks like it's coming from the transmission side--you'd really have to get it up in the air and follow the leak to the source and fix it. Hard to do these type of repair on the ground... You may have to clean around, then run the car to see where fresh leaks are coming from.

 

thanks anyway i do know i need a lift to do this just thought i would put it on here just to see if there was a common problem with the 240's leaking when put in gear no leaks at idle in park ... your time in helping me out is greatly appreciated

 

for sure there's a lot more pressure when driving, while idling, the fluid is just lazily circulating through the cooler.

 

Hey pierce,

i was just wondering why it dont leak in park ..ill get it on the lift and have someone in the car with it in drive and brakes on

 

A few years back our 740 leaked right under the clamp. It's a good place for dirt/mud/salt to impact and rust out the line. If you remove the clamp I bet it will leak. For a quick fix you can cut the lines and put a piece of rubber fuel hoe and a couple of clamps. You can also flair the tubes and splice in some tubing or put a compression fitting on. The easiest way is to replace both lines.

 

It's actually quite common up in the rust belt to leak around the clamp. Vibration over the years can cause wear on the lines at the clamp. Combine that with the salt, you get corrosion at this point. I have had to replace it on one of my 240s due to a leak at this point.

 

that's what i was saying i stumbled across a few links on the net and mentioned that these lines leaked their at the clamp...just want to get her on the lift to get a good look
