MT82 3rd and 4th Gear Failure

[Crimson18PP]

I have a 2018 GT Premium PP1 with the manual and lost 3rd and 4th gear today at about 74,000 miles. I have an appointment at a local Ford dealer to have them look at it this week and an aftermarket warranty which should pay for needed repairs.

My question is what else should I have them replace/inspect while they have the tranny out? Clutch, throw-out bearing, and flex plate?

It would definitely be a good idea to replace the clutch, flywheel and slave cylinder. I would also have them replace the rear seal as well. You’d hate to have them do all that work and not replace a seal with 74K miles on it because it developed a leak shortly thereafter. That wound be more money, as everything would have to come back down, in order to get to it.

If the tranny work is covered under warranty, you’re good there. The clutch and other items will be on you though, so be prepared for that.

That sucks you lost 3rd and 4th. Any prior symptoms or did it just crap out? I agree w/ NGOT8R, a lot of the expense is labor just to drop the transmission and if warranty is covering that you might as well replace the wearable parts: clutch, pressure plate, flywheel, throwout bearing, pilot bearing, rear main seal, slave cylinder (maybe). Don't forget new flywheel and clutch bolts as they are one time use according to Ford. Probably looking at $1k at least in parts alone for new OE for all of this. 74k miles shouldn't be that much for these parts, but this would be the best opportunity to replace things.

Been thinking about a short shifter? This would be the time to have it installed.

Thanks for the responses. I was also contemplating an MGW short throw shifter.

As for symptoms, not really. I felt some driveline slop/clunk when shifting at high RPM's into 3rd. But, never really had problems shifting into any gears. (No lockout or grinding)

An OEM clutch and flywheel was over $2k when I had my slave cylinder die last year.

I think I paid $2300 for my Ram Pro Street cerametallic twin disc. I mentioned replacing the rear seal. I purchased the MMR billet rear seal plate and seal combo. The seal looks to be of a much higher quality than the OEM. One more thing that would be a good idea to replace while the tranny is out is the crank position sensor. You’ll see it in the pic with the billet rear seal plate at the
1 o’clock position.

For a more detailed look at the inside of the MT82-D4, take a look at my rebuild thread. If the dealer doesn’t warranty the work and you have to pay out of pocket, I highly recommend upgrading some of the things you’ll see contained in the thread.

Last time I checked a dual mass flywheel listed for about $1200 by itself. Ford considers it a wear and tear item that should be replaced along with a clutch replacement. Lol.

If your MT82 has never been opened up, this may be of interest to you; Ford knew of the shift fork issues early on.

I do not know what leverage you will have with 74k on it BUT you could use the TSB info and call the Ford Customer Service #800 and see if they will help with the cost of repair.

I just put in a Mcleod RXT twin ceramic disc with the aluminum flywheel and the new braded hydraulic line, the clutch was $1300.00 with the hyd, line. I replaced the stock MT82 and installed a Calimer stage 2, $3300.00 for the transmission. I am about to change fluid, brake in is complete. I am going with BG synchro II 75/80 gear oil and the cost was $50.00 for two bottles. I also replaced TOB the cost was $77.00, pilot bearing and flywheel bolts. The pilot bearing and the flywheel bolt, from Ford the cost was $66.00. I like the clutch and it is not noticeably harder to work than a stock clutch. It is a nice and a positive clutch. I also have the Barton Industries stage 3 short throw shifter my shifter was $420.00. I did the work myself, so I had zero labor cost. Total cost $5213.00. I am 74.

With a stage 2 tranny, will you push the tranny hard or did you just upgrade for peace of mind?

 

[Craig Brown]

I drive it hard but mostly I wanted to upgrade the MT82 with a better version of the MT82 and yes peace of mind entered into the equation. When I want to push it, I don't worry about the clutch or transmission. If I want to add more power than I have now I will be ahead of the game. It is at about 460 RWHP now N/A.

I bought the car used with 31K on it after I started to add power to it the second gear started to pop out when I would down shift or if I would drive in second gear and let off the gas it would pop out of gear. I knew I had a synchro issue. I could rebuild it but if it crapped out in the first 31K, it was time to look at something better

Good call for sure .
