The 5.29 Mega Thread!!

I know this has been discussed and answered... but, what temps are ya'll running at highway speeds? Hit 200+/- several times running 60-65mph. Finished my 500 and fluid change. Fluid was extremely clean and drain bolt had hardly any shavings to my surprise. Still running pretty high temps even after fresh fluid. ECGS said these temps were considered normal. Any thoughts?

FYI my gears seem to be very quite. No whine on deceleration, but hard to tell with MT's. On a good note, I actually enjoy driving my truck again

 

That whine your hearing, is straight up a big set of balls now lol

 

Just got my gears and bearings back form Cryoheat in Oceanside, CA. Micro polished gears and cryo treated bearings and gears. Josh there sounded tired every time I talked to him on the phone. They reduced there employees to only one person in the shop at a time and multiple shifts a day, every day. My hats off to them.

I’ll install these, most likely, when/if Constuction gets shut down in Los Angeles.

Eye candy for now. Be safe everyone.

 

Ho everyone long time lurker first time posting and going through all these post is super time consuming I just had my 5.29s put in yesterday. I'm not sure if I trully feel a difference in the gears or maybe I havent driven it enough just did the first 50 miles im running 285/70/r17 bfg k02 on 3 inch lift im in Georgia, and going on 985 for those of you who know is some what rolling hills and im sitting at 3400 rpm at 70 going up a tiny slop thats feels just like my stock gears or is that normal i got then to solve that issue but maybe I am misunderstanding what these gears are trully meant to do getting only 14 mpgs combined was orginaly getting 13.5 so it went up a bit and i have a rtt and some rock sliders and a prinsus rack and awning but ill be adding a lot more weight in the near future so if any one running a overland setup with 34s can chime in and see what your avg rpm, and mpg is id appreciate it

 

I have heard some disconnect the positive lead for a bit, and allow their truck to relearn driving patterns.
Just a thought...you know these trucks are more computer than anything these days.
This could make a change, however you and I sound like we have a similar rig. I felt a good amount of difference in shifting and pull.

 

Ill try that see what that does, also fyi when i go down 85 my mpg changes to about 17mpg ive notice that over the past couple years so i hate driving 985 just for thay reason alone lol, but what are your mpgs and rpms at highway speeds like?

 

Not that it's going to help you, but this is where OVT clearing learned values helps. But really does sound like a) you should break it in b) get a tune and make your engine and gears come alive.

 

Yup. I have heard the recent Tune for the 5.29s made the trans even better. I will look into it after the TacoBox is paid for

 

Great thanks for that info ill definitely be doing the breaking in correctly also as far as the front gears i was seeing some people breaking them in on pavement and others advicing against this i was going to go up to helem and put it in 4x4 on the forest service roads to break them in would that be a good way to break them in for the front I mean

 

Indeed that would be the perfect way to break them in.

 

Thanks i figured it be less strain on the gears in less traction environment for the gears not to work so hard

 

Does anyone know of a good shop to gears in or around the San Fran area?

 

Does anyone have the 5.29 gear tune for 2016 04b04 AT. If not what tune are you running?

 

I had the test tune for 5.29’s but I’m running the 19800 for 4.88 until the final comes out

 

how does it drive on the 4.88 tune vs the test tune?

 

Does better on the 488 and Matt told me to stop running the test so I did

 

got it simple enough haha

 

These guys did my Mustang gt500 and I had no complaints...
