  1. 10R80 swap to a 6-speed manual

    Well I refuse to buy a muscle car that may have been beaten on by someone and they don't make the Mach 1 model anymore. About the only new Mustang I could buy with a Tremec transmission is the Dark Horse, and what they are asking for those is ridiculous. You have to wonder why Ford puts the...
  2. 10R80 swap to a 6-speed manual

    Thanks for the information, that was very helpful. I'm going to abandon that idea as I believe you are correct abut the $15K to $20K cost. I never considered how it may tank the resale value and I'm sure it would. I would buy a new GT if Ford would only give us the option to order one with a...
  3. 10R80 swap to a 6-speed manual

    I have a 2018 GT with the 10 speed automatic, prior to that I had 2 mustangs with the Getrag MT82 6-speeds that I was not enamored with. I was sold a bill of goods by Ford telling me how good the 10R80 is, and it is when it works. The problem is that it has a couple of design flaws and from...
  4. Race on Sunday, sell on Monday

    The only option I want in a GT is a Tremec transmission. Ford knows the MT82 is junk and that is why it is not in the Dark Horse, Mack 1, GT350, GT500, etc. A GT with an option to order a 6 speed Tremec would push me into buying a new Mustang to replace my 2018. I'm not going to spend $70K on...
  5. Thoughts on a '21 GT Premium PP1

    I'm always leery of buying a high performance car from anyone other than the original owner. This car may have been owned by two people who beat the hell out of it. It looks like a nice car and if is still has the powertrain warranty it would make me feel better but you just don't know how it...
  6. Oil - Type to use and best

    I usually want to be correct when I make a statement and I remember reading that too thick an oil cannot get through the small passages in the cam phaser so I went online and checked it out, the answer I got is below. In addition if the oil pressure is higher than what the Engine Control Unit...
  7. Oil - Type to use and best

    I'm no exert on cam phasers but I remember reading, or seeing, that using a thicker oil may affect them negatively as oil pressure operates them. I think the owners manual says that you can use 5W-30 if you are going to race the car but at the next oil change go back to 5W-20. I think that the...
  8. Oil - Type to use and best

    Everyone is going to have their own opinion on this and no one will ever change their mind. In the past I used Mobile 1 full synthetic 5W-20 in my 2018 GT. Recently I changed to Valvoline Restore & Protect 5W-30. My reason for going to R&P is that auto manufactures are using piston rings with...
  9. Question about our automatic transmissions.

    I don't know the real reason but it seems to me that since cold water sinks putting the transmission fluid at the bottom of the radiator means it will cool the fluid better.
  10. Aluminum 10r80 Pan on RockAuto

    I contacted PML a few weeks ago asking them to produce a pan for the 10R80 that has a stand pipe built into it so it would be much easier to get the correct fluid level in the transmission. I believe the GM 10L80 pans have this and all you have to do is fill the trans up and get it up to...
  11. Oil Pump Question

    I would soak it in oil if it was me. What can it hurt to pre-lube it.
  12. 2019 mustang gt 10r80 power lose

    Could be a lot of things but we do have a drive by wire gas pedal. Sometimes they can get sluggish, you may want to start there.
  13. 10 Speed Owners... please talk to me...

    My 2018 has the 10 speed with 66K miles on it and so far no complaints. I did, however, buy it new and have taken good care of it and hardly ever abuse it. There are some design flaws with the early 10R80 transmissions and if yours was driven hard the part they call the "trash can" inside...
  14. Found crank gear teeth in my oil pan during last oil change

    There is no way of telling how much damage was done to the engine without tearing it down. If you warranty will only cover replacing the part that is damaged you should get some type of assurance, in writing, that any future problems that are found will be covered. If there are metal flakes...
  15. Random 10th gear slip and high trans temp

    I also read the problem with the fluid being too high is that it gets up into the planetary gears and it froths it up, which cause a whole other set of problems. You may have seen my thread about having a pan produced with a standpipe in it to get the fluid to the correct level easier. Many...
  16. Random 10th gear slip and high trans temp

    The procedure to check the transmission level is cumbersome, I have attached a PDF with the correct procedure. From what I have read the temperature may go too high if it is underfilled. I bet the dealer never let it warm up to the proper level when he checked it. There are some good...
  17. Can a standpipe pan be designed for the 10R80?

    Since I started the post I have been in communications with PML who produces transmission pans for many makes and model cars. They seem genuinely interested in adding a standpipe to the aluminum replacement pan that they make for Mustangs equipped with the 10R80. I'm not sure if this will...
  18. Can a standpipe pan be designed for the 10R80?

    I have been asking this question for over a month and can't get an answer to it.. Ford doesn't say anywhere that I can find what the cold level should be and I am of the conclusion that it may vary depending on how much drains back into the pan. On different Mustangs they probably have...
  19. Need dipstick length on 5.0 Coyote gen 3 with 10 qt pan

    Cars are sent to the dealers with all the fluids in them, including oil and some gas. They have to be able to drive them onto car carriers to get them there and drive them off.
  20. How is this possible?

    This whole thing stinks to high heaven. If it was me I would take the car to an independent tire shop that you trust and explain the entire scenario. At the very least ask them to balance the wheels and see if they can. If they can't they should be able to tell you why.
