Update on that bump issue, My 2010 XLT with 5.4 is smooth as silk. The ford rep told me today that BUMP at stops was ''normal" and I told him that my 2010 don't do it. He said the trans where differant than the 2010. Maybe my ordered 2012 Lariat wont do it?? I told him that I was told ford fixed that issue. I think is is BS...

 

I thought the 2011-12 trannys were different thant he 10's

 

I thought they were all 6R80E's?

 

They are

 

Clutches are differnt.....ratios and stall on the converters......list goes on lol

 

The case is the same.....all 2011 and up internals are differnt. They also dropped the "e" on the 2011 up.

 

Yes that is what he told me also. They told me it was (normal)??

 

I don't think it's normal. Just now I went into a parking spot and right when I came to a stop I had a slight clunk with the bump. I'm going to take it back to the dealer. Again. It seems that Ford has one of the worst drivelines here recently. I love my new truck but I'm not going through this again. Like I said, I'm a die hard Ford fan but these past two trucks have left a sour taste in my mouth.

 

One or two piece drive shaft??? Whats your wheel base?? I know that the 157" wheel base is the most noticeable due to the clunky two piece drive shaft. Also the rear end hear has a impact on the subject as well. The steeper the rear gear ratio the more it can be pronounced.

You should take a ride in my 2012 5.0 auto stang.....you think your trucks bump....try the stang......4.10 gears with a 3500 stall converter lol. 6r80 trans as well. Nature of the beast. Ford put tough clutches for the trannys not to fail.......the tougher the tranny the more you will feel it.....the new 6r80 is designed not to slip at all.....unlike previous models with less of a first gear ratio and looser converter.

 

There is nothing normal about this. Its a shoddy design and its what happens when you try and retro-fit a "new" transmission into an old case.

This is unacceptable for a truck or any vehicle to do that.

I had mine serviced and they were able to take care of it with lubing the slip yoke with some special blue grease and replacing the boot. The 157" WB trucks are more prone to this issue due to a 2 piece driveshaft. I am not sure of the TSB, but there is one out there for this.

So, after mine was taken apart, lubed and put back its gone, along with the newest reflash as well. If thats the case then how is this normal?

I love you guys that take the bait that its "a normal operating characteristic of the vehicle." I bet you guys had your lunch money taken a lot at school.

 

Maybe it is normal. Normal for a poorly designed tranny. Going in next week for the 2nd time.

 

No bait taken here.......us Mustang guy's love them. One of my buddys is making over 600 rwhp and 500 ftlbs of torque at the wheels and not a single problem. Im pretty close on my stang on the bottle to those numbers.

So ****ty tranny....to me not so much, I love it lol, strong as hell, and very precise.

If you do infact do have a problem, and you have to take it in more than twice.....find a dealer that knows what the hell they are doing I hate to say it but delears are just parts changers, if the ford hot line doesnt have a awnser the tech wont have a friggin clue, and he or she will take it apart for nothing....why be a guinea pig?

Or buy a tuner/programmer and set the way you want it to shift to your likings. Several good tuners out there for the 5.0 guy's

 

As far a the comment "new tranny shoved in a retro case" is just retarded. Just like having the same model truck but a eco vs a 5.0 same shell yet differnt internal's/engines.

You guys are cracking me up lol

 

Also for the guys with the 157" wheel base there is a tsb in regards to you possible problem. They put shims on the rear end to adjust the pinion angle to cure a bump or shudder. It is not a tranny/programming problem though which many seem to confuse the two.

 

How is it wrong? The case is an old model and they made it into a 6 speed, therefore things get smaller, and less robust.

Your comparison makes no sense.

Wrong.

The pinion angle shims is for a take-off shudder at low speed, not the bump stop. It also includes a new tranny mount and new springs, none of which work or fix that or the other problem.
