Transmission fluid videos

Part 1

Part 2

Differential fluid

It sometimes amazes me on what gets commented on in my videos sometimes, such as my ‘dirty engine compartment’, no worries one thing at a time. I thought I would touch on some of the comments in both the transmission fluid change and differential fluid change videos with this video as there were some good points brought up. I appreciate your comments and your input so keep it coming.

  1. Hey Eric, Thank you for making the video, I'm sorry you have to put with the petty critics. Thank you for sharing you knowledge and take the time to show and share (in real time) the efforts and difficulties of the maintenance vehicles. I know you have demystified what some of the shop manuals don't cover/leave out and taught me trick and tips for working on my 94 Accord..changing the front rotors, cleaning the EGR manifold and the Automatic Trans. naming a few. Again! Thank you!! Keep up  the Good Work and  Stay Dirty!

  2. Dude it's nice to see someone that that tells it like you do. If the trans is slipping, then you put awesome new fluid in the the vehicle doesn't move any more, it does not work any more. Lol. Anyone that thinks that any snake oil will fix it… I just don't know what to tell them.

  3. " It's rust protection" my thoughts exactly! If the rear main engine or transmission seal leaks on one of my cars, I just consider it an automatic undercarriage oiler. As long as it isn't leaking so bad that I have to add a liter a week, I'm totally content with it.
    Although most of my vehicles don't have cats anymore. Oil dripping on a properly working super hot cat might not be a good idea lol

  4. both of the cars ive owned (and own) first being a 1999 camry and my current being a 2009 fusion have the rubberband harsh shift effect but neither slipped nor did their fluid smell burnt nor do they have delayed engagement etc just those hard shifts, i replaced the fluid in the fusion with a generic (but upto spec) fluid and changed the filter and it got better then went back to the same, changed it out with oem motorcraft fluid was WAY better now its the same again, gonna do a home flush through the cooler line with the OEM motorcraft fluid, only 60,000 miles too filter did look clean and the magnet didn't have a significant amount of shavings and none of them were large. very frustrating.

  5. Every time that you changes the fluid and the filter just opend the old filter and look for clutch material if you have clutch material just put the new filter and use the old trabsmission fluid because the new one would destroy the cluthces because of the cleaners and etc.

  6. Noise when shifting gears only lasts a second, its like it takes time engaging gears. 1st gear constant noise, but engages right away.

  7. I know this is an old video, but I feel the need to correct you on the power output statement you made. You mentioned the transfer case clutch and how it sends power to the front. that's incorrect. the 4EAT transaxle is the same whether AWD or FWD with the exception to the AWD clutch assembly located in the rear housing of the transmission. Essentially the AWD clutch activates the REAR wheels, not the front. the 4EAT is inherently a FWD transmission ALL the time and has solid connections to a driveline inside the bellhousing that connects the rear output to the front differential. It is only when the front wheels slip that the AWD clutch engages the rear driveline thus supplying power to the rear wheels. This tech has been implemented since the mid 80's and has been carried through to current models with various other modifications.
    The 4EAT is actually one of my favorite transmissions to rebuild and they're less complicated than people think. In fact if you want to take the rear driveline out and make if FWD only all you really need to do is take out the rear housing and clutch assembly and reinstall a case plate from a FWD Subaru all while still mounted in the car with no internal modifications.

  8. FWD fuse is a great tip, so many people I talk to didn't know they had this. Part of this may be because it is only mentioned briefly (in my case) in the manual's section on the spare tire, because the car should be switched to FWD when the donut is on to prevent strain on the AWD system.

  9. from 7.04 whats with the tool on the wall to the right of erics head swinging on its own for the remainder of the video. ooooooooooooo.

  10. I am not one of those guys who has a spotless engine either. I have no leaks that I am aware of. My 06 Jetta 2.5 has 130,000 miles and still runs like new. I might not be one of those people who keeps it spotless under there but I do change the oil every 5000-7000 miles. I also change the transmission fluid. I don't wait for it to turn black and ugly and fowl smelling because by then the transmission is ruined from lack of maintenance. I prefer to do the transmission fluid every 30,000 miles or maybe a little bit sooner, it does not last a life time and no fluid lasts that long. I don't care what the car dealer tells me, they just make it sound like the car needs less maintenance so more people buy them.

  11. Hi Eric,
    Thanks for your helpful videos. My 1998 Legacy has the opposite problem to torque bind – no drive to the rear wheels. After almost a year of studying forums and asking questions I went ahead and removed the transfer case off the rear of the auto trans. The duty C solenoid was functioning as expected – normally closed, and open with 12v applied to it. I can just hear a tiny leak while blowing through it while in closed position. The metal plate between the valve body and the transmission is weird though – the only way for the oil to get to the solenoid switch and escape out into the main oil chamber is via a TINY hole in the plate. There are no gaskets either side of it. Another strange thing – now, for the first time ever, I have the rear drive shaft actually engaging the front drive shafts. The oil is drained from the transmission, and the clutch pack is somehow engaging. What is causing the clutch pack to disengage when the engine is running?

  12. great videos, been following you for a while, your a good talker and quite smart, seem way to smart to be a mechanic.
    i've learnt quite a lot 

  13. hey eric! quick question i have a 2002 Acura RSX base model the previous owner installed an lsd now few weeks ago i started hearing a mild grind when shifting at high rpms into third and i want to swap out the trans for a used one but i take it i will loose what ever he installed or is that separate from the trans?

  14. Eric, we were able to solve our torque bind issue by replacing the solenoid that the FWD fuze goes to.  It was a pain, but it worked.

  15. #2 – I run the car for a week then removed some more of the fluid (about 1/2 a cup) and put more lucas in and ran the car again. As it leaked down some i added more lucas for a month or so and then it stopped 90% of the leaking! It was really leaking bad before using the lucas. It has been 3 years and still doing good. I have not added any lucas in those 3 years. I have just been adding regular power steering fluid. This is a 91 nissan. I can say for sure lucas does work on 1991 nissan seals.

  16. #1 – I agree the dirt on the outside of the engine does not hurt anything. It just does not look good. Now lucas power steering stop leak does really work very good! I had a bad power steering leak that nothing would help! On my nissan. I used 3 different kinds of stop leak including the split bottle kind. I thought i was going to have to put alot of work and money to fix the leak because it was comming from the rack and pinion! As soon as i put the lucus in it stopped 70% of the leaking.

  17. hey, eric when you're discussing new trans fluid,,, wet and sluggish,,, your expression was leaning toward sexual connotation. lol.

  18. There's not a thing wrong with breaking the drain plug loose first, just don't let any fluid out until you've got the fill plug loose as well. That's been my experience.,, This way even if your fill plug won't come loose you can just tighten the drain plug and deal with it another day.

  19. Just FYI, I believe the old 4EAT's like in this video use the MPT Clutch system to send power to the rear. It uses a transfer duty solenoid and fluid pressure with the MPT system to send power to the rear. By putting in the fuse, it cuts off the fluid to the MPT, killing power going to the rear. The front should be mechanically driven.

  20. You can also find some ice and floor it and look out the windows to see if your throwing snow from both tires. Also a good way to check for a limited slip lol
