How to Replace a Transmission (Full DIY Guide)

  • Published on Jan 1, 2019
  • Transmission removal, replacement, and installation. Learn how to remove a transmission so you can replace your clutch or flywheel, or so you can rebuild your transmission and install a new one in your car or truck.
    In this video I show you the 10 simple steps on how to replace a transmission. I am doing this on a rear wheel drive 98 Mustang but the process is very similar on other rear wheel drive, front wheel drive, and even automatic cars and trucks. Each detailed step will allow you to learn how to remove a transmission yourself so you can replace a clutch, flywheel, rear main seal, throw out bearing, pilot bearing, or just swap transmissions.

    To answer the most common questions in the comments section:
    1.) Quality videos like this take a lot of time to produce. This and the next took me over 300hrs.
    2.) Follow me on Instagram "ChrisFixit" for daily updates and tips and tricks.
    3.) The exhaust on the car is the performance exhaust, just used on the track.
    4.) The speedometer is fine... it spun all the way around at the last drift event and I havent had a chance to take the gauge cluster out and push it back to the other side of the peg.
    5.) The other red Mustang is from this video:

      Hi I don't know if you read these with so many viewers. I have a 69 Nova with a 500 hp 383. I got sick and can't work on it anymore. It needs a new wiring harness, which I have. I live in Costa Rica. I have my dream car and can't do the work. Maybe some would like to visit the country. I have all the tools and room in my house. They could have a great vacation and help me with my car. Hope to hear form you. Great vidios...

    You really don't need that many "specialized" tools to fix the internals on a transmission. Especially a manual. Manuals are very simple inside. Two bearings on the input and output shaft. A couple syncronizor rings and a few shift forks that move the syncro rings. The hardest part is lining up the input and output shaft correctly with the counter shaft. They're intimidating, but actually quite easy to fix.

    Knowing me, I'd die just doing step 1 wrong. My car is at an autoshop in surgery right now. I thought for about 2 minutes that "maybe" I could do this myself instead of the scary price I was quoted. But noop. I'm sure some can do this...but I have little faith in

    That transmission jack is terrible with larger transmissions. It sways back and forth and causes the transmission to fall... so be careful, also what's with the towing strap or did you forget about it

    I rebuilt my front wheel drive transmission GM 4t65e without removing it from the car. It was too heavy, so i removed the driver front wheel, lowered the engind down by loostening the sub frame bolts and lowering it down on wood blocks, removed the side case, the pulled out the guts. I needed new clutch packs with 185,000 miles. I never saw the inside of a transmission before. I used a shop manual from a closed GM dealership i bought on ebay

    Like how ChrisFix is wired, he makes things clear, and focuses and how things should work, not what can go wrong. Fact of the matter, if those 10 steps can be done under 10 conditions, go for it. My 10 conditions are as follows:
    1. Need to have a backup car to drive
    2. Car needs to be enclosed in a location that can be worked on during evenings, like a garage
    3. You need to give yourself two weeks to do the job
    4. Allow yourself to complete one step per day
    5. You need to have a backup plan if you fail or quit. Know in advance what mechanic you going to ship the car too and how.
    6. If you send it to a mechanic be prepared to buy a rebuilt or re manufactured tranny because they warranty their work and dropping a transmission for defective part could be an enormous financial loss for the mechanic if it doesn't solve your problem.
    7. Play music to keep you relaxed
    8.Don't MacGyver any step, buy the right tools for each step
    9.Understand the number of other jobs and part replacements (i.e., starter, seals, mounts, drive shaft, muffler, etc.) that should be done while tranny is dropped
    10. Cannot be rushed. Must be treated like building a model airplane

    These ten rules can save you thousands of dollars by doing the work yourself. Worse case scenario you wasted many hours on something you could have paid a pro to do in one day for a premium cost. It's a dilemma.

    • Diy_Automotive
      Diy_Automotive 11 days ago

      On an automatic you will have a shifter cable normally bolted to the side of the transmission that you will need to undo. You will also need to remove the cooler lines, and unbolt the torque converter.

    Hey Chris, I never saw a manual transmission take ATF fluid instead of gear oil. Although I had a 1959 MGA that took 30 Weight motor oil.

    • Diy_Automotive
      Diy_Automotive 11 days ago

      A lot of newer manual trans take auto fluid, the clearances are much tighter and require a thinner fluid
