Transmission cooler line replacement

I'm so glad you were the 1 to respond to me cause you and I have been dealing with this truck for almost a year now with the power steering rack and pinion and so much more so let me start at the top and work my way to now lol ok so I bought it and the power steering pump was going out so I had an idiot to change it only after her did it began leaking fluid so in trying to find the leak I discovered in fact he hadn't installed it right and it was now damaged so again I replaced it still it leaked after discussing the issue with 1 of your people I was told it was likely the hi pressure line or a connection to it so I replaced the line and still it leaked from somewhere up top but not at the line or from the pump so I took it to 2 different shops that said it was my rack and pinion, so I replaced it with a used one as I couldn't afford a new one and still it leaked mind you my truck never had any issues shifting into any gear but it would make a grunting noise and not jerk but similar to surging from time to time but only when I was coasting which began getting worse when the city started taking up our streets leaving us to drive on extremely dusty rock filled streets. So I took it to Aamco explained what it was doing and asked them to drain the transmission fluid and refill it and to run a computer diagnostic on it keep in mind I have taken it to them at this point 3 times to do what they call a complete vehicle inspection because of everything I just told you and not 1 time did they say anything about my transmission so this time when I go to get it they say they didn't drain or refill my fluid and they didn't say if they ran a diagnostic or not but that they hooked it up to a code scanner even though my check engine light wasn't on and that it threw out numerous codes and that my transmission was shot and was $6,400.00 had to come from Nissan and be brand new can't rebuild ether now that's an issue for me on many levels as my truck was shifting and driving fine before this every now and again the rpm's would go to a 3-4 but not often keeping in mind that when I took it to them it had less than a 1/4 tank of gas in it and almost empty when I picked it up within the 1st 24hours I didn't drive it much so I didn't put gas in it on day 2 of me picking it up I drove it maybe 15 to 20 miles and the gas light came on now I only get my gas 1 place but wasn't near there so I only put 5or10 in it and it began to rev really high and actually jerk not surge but jerk so I drove it home and I parked it mind you it was still shifting into gear and going just fine outside of the revving and jerking that was alarming but not so bad I felt my transmission was going to stop so after about 2 days of waiting on parts that I learned could be the cause I changed the transmission output sensor all my plugs air filter throttle body hasket breather tube and cleaned my air intake housing throttle body and changed the oil and coolant went to drive it and it wouldn't accelerate past 10 miles per hour and the RPMs stayed below 1 so I parked it then drained the transmission fluid that was black almost and the tranny motor mount and now the rpms go between 1 and 2 still shifts into gear fine but accelerations the same when looking online its says it can be due to low fuel which it is or an air fuel leak bad fuel pump a bad transmission cooler o2 sensor low transmission fluid which it is it takes over 10 qts and I only put a gallon jug in it. I'm waiting on my Lucas CVT fluid now to finish filling it up. So, now with all of this explained do you still think it's my transmission and finally I don't know what or how to do the test to find the leak of coolant that only started after the mount change. Can you elaborate on it for me and thank you so much for this site.

I can't find the 1st location of the transmission speed sensor that's near the front of the tranny by the battery or the PVC location. Can you show or tell me please?

I changed my transmission mount and afterwards I started it to see how it did and coolant was streaming out from underneath it. So, I got under it and can't see where its coming from exactly but it's somewhere by the transmission as for the shifting its doing this just fine in all gears however it's not accelerating passed maybe 10 MPH and revving from 1 to 2 the reason the 2 are combined is because they both became issues while trying to fix the loss of acceleration and RPM issues.

I'm going to have to go buy a tester first.

Okay. So, I did the pressure test and bits defiantly coming from the transmission area like maybe the cooler lines if they run through the inside of or on top of the transmission pan. So now I need to know how to repair this without damaging anything else cause my other issues may be fixed because I did a code scan on it and was getting throttle body related codes and when I was taking it apart to get to the throttle body I found I had forgotten to plug its harness back up from when I had changed its gasket recently then I backed out then in my driveway it accelerated it is making a weird sound that I will send a video clip of shortly. I've read though that when your alternator is failing sometimes it will make sounds and cause leaks that mimic a failing power steering pump drivebelt and even transmission. Do you think this can be true cause? It would really explain why I went through 3 new power steering pumps a new high-pressure line replaced the rack and drivebelt and I still here the whine. And have the leaks and nothing i've done to stop has worked. But please inform me of how to replace these transmission cooler lines please and thank you.

I don't know what just happened but I just spent the last 20 minutes in detail and hit send yet even after logging off and back on. It's just gone, no post whatsoever, ugh. Anyways I did the test and like I said before its defiantly coming from the transmission cooler lines that I'm guessing run inside or somewhere around the transmission pan. I can make a video but it will only show the drip you can't see the actual spot if I just pinched it can I mend it with jb weld steel or something like it or do I have to change the entire lines and or cooler?

It is not possible to see where it is exactly coming from unless I remove the transmission pan meaning redraining all my fluid because its coming from inside of that area, and mind it was not leaking any coolant at all ever before I placed the jack underneath the transmission pan to replace the mount. Which is why I'm saying I had to of pinched or pierced a hole in the transmission cooler line on the inside. I've already returned the $200.00 test kit to Orielly's because I saw it coming from the same area as it was when it was started the first time after changing the mount. So, what and how exactly do I take a picture if I can't see inside of the pan?

What I said was after changing the transmission mount and starting it there was a steady stream of coolant coming out from underneath. You said do a pressure test on it and I did with engine off and cold through the radiator cap and it got to between 14 no higher than 16. The stream became a flow of coolant I removed the test and it stopped as for transmission fluid. Yes, there is a small steady drip coming out however these leaks are nowhere near each other the transmission fluid scratch most of that look at the videos after I climbed from under I notice that 1 of the bolts to the mount is not screwed in right so i. About to redo them and lyk after where i'm at.

Okay. So, after redoing the mount it's still leaking the coolant as I showed in the video so is it likely I have damaged the lines. What your thoughts now?

I understand you can't tell me where its leaking from and I got under it and with my hand followed it up as far as my hand could reach which isn't far as I have t-rex arms, lol but as I went upwards I noticed that where the CV axle goes into the tranny from the passenger side just at the entry had what looks to be fluid coming out of the entry is there a seal that may of came off there just curious anyways so I went a bit further up from that point on the back end of the transmission kind of and I don't see any coolant lines in the area. I will get under it and make a video and try to get a better view of it I did however read online about there being a coolant hose that supposedly runs under the manifold to the back of the air intake that can leak and make it seem as though its coming from the transmission area but isn't. It just puzzles me as to what I could of pinched that hi when I jacked it up to do the mount because it wasn't leaking any coolant at all before I changed it. So, I guess until I send the video if you have any thoughts or suggestions so far I'm open to them otherwise I will wait and see after the video, but I did do the pressure test and I couldn't see the leak location ether ttys.

Okay. So, I'm put here on the truck and I took off the air intake and air filter box and found a puddle of antifreeze under it and on top of the transmission kind of that has hoses that connect to the throttle body in the video I included. I will try to talk loud and explain in the second video does this hose looks to be bulging to you or that they may be bad. However, I think that I may of hd the hoses that connect to the throttle body hooked up wrong do I switched them and will put it back together and lyk what I discovered but let me know on the hoses and video 2 on need to replace or not please.

Okay, I will do that in the morning and let you know, because after putting it back together and letting it run for about 15 minutes it started doing it again and smelling as though something was burning. So, I may have to swap the hoses back on the throttle body to how they were before but I will let you know afterwards.
