How are your trannys holding up????

[twintips_17]

Im looking at buying an 05 PSD and i want to konw how everyones trannys are holding up after an intake, exhast, and chip. I have heard that the ZF6's go through clutchs easy with all the torque but that they internals hold up great. I have also heard great things about the 5R110 and that it handles the power ok.

I was born an raised running 5spds in our 7.3's and would like to stick with it. I dontdrive too hard on my truck now but i do like to get up on her and be able to show whats up. Im looking for the most bullet proof tranny that will last me a long time.

I am very familier with changing clutchs and am not wary of doing it in the future. But if the auto holds up better in the long run i might want to get it......

Also how do you guys that have the ZF6 like them. I have heard mixed reviews about them. I have heard that the 6.0's power band is better with the auto.... Doesnt make any sense to me.

Throw all the info you got my way....

ive seen the 5R110's hold up GREAT....ive only seen three replaced and all of them were abused....overheated...etc... (one had a case so packed with mud that you couldnt see the case...obviously it overheated...LOL)

5R110 on mine and 30,000 hard driven miles...mostly on tunes..so far so good.

Well my 5R110 in my 06 F2Fidy... i've made easily over 20 quarter mile passes and drive my truck like I stole it on a daily basis and I'm running Innovative's Xtreme Street tune with AFE stage 2 intake, MBRP straight exhaust, plus all the other mods in my gallery list. I run this rig hard! On 35" tires too.
Tranny shifts firm and strong and never lets me down! Have 59,000 miles on it too! going REAL strong... I would say you're going to be good with the plans you have!

I have 52,000 miles on mine and run the crap out of it. No problems so far!

110000 miles on mine about 80000 pulling a 26ft 5th wheel and about 30000 tuned to the max. Still shifts great and runs cool. Great transmissions!!!!.

So i have heard a lot about the 5R110.... How about the guys running the ZF6????

[dhanna6powerstroke]

I've never ran one personally, but have plenty of friends that do. The clutch is the weak point. All the guys I know replaced the stock clutch with a South Bend unit. They can make the clutch as strong as you want. They've not had any trouble with the internals. The hydraulic clutch line w/reservoir goes bad if it is not the updated 1 piece style, but other than that, awesome tranny.

I upgraded the clutch in my F150 to a center force when i put a new tranny in and would never go back to stock. I love the center force. Im torn about what tranny to get.

Are there any major TSB's out on either of the trannys.....?????

[dhanna6powerstroke]

Not any on the ZF that I am aware of. The 5r110 had a recall not to long after they came out, but it was for the planitary set. As far as I know they have all been repaired. I worked at a Ford dealership for a while and we only had 5 or 6 5r110 come in for the recall. None came in with actual trans. concerns. I did however see one the other day at the dealership I worked at with the case broken. The guy was an idiot and told them that he just installed the biggest chip Bullydog makes and drove it on the highest setting without training the trans. Needless to say, no warranty for him. Just remember to train the transmission if stated in instructions.
