Shifting from 2nd to 3rd under hard acceleration.

I have this problem of shifting from 2nd to 3rd over 5500 rpms. Below that it's fine but above that you have to give it a second before it will go into 3rd. Anyone else get this?

Yep alot of people have that, until you get a new shifter bracket or new shifter. I went with the Steeda bracket due to its low NVH level. There are many others Barton original and two post, JHR, and even a energy suspension bushing that goes into the stock bracket. Some do a complete shifter swap to MGW or Hurst. I missed 3rd quite a few times until the new bracket, although I wouldnt really call it missed, more like it would not go in at high rpms.

Yep, it's a gear block. Caused by the mis-alignment created from the remote shifter mount being attached to the body and the torque of engine/trans under high revolutions, contrary to what other may "feel" and think, a new bracket or mount to the body of the car theoretically will not remove the misalignment, . With that said, a different shifter may provide some additional wiggle room, but I have no idea what a firmer bracket bushing could really do to help.

I still get it, although I'd say it's on shifts higher than 6500 RPM's for me. I'm using a different shifter assembly(Hurst) and the stock(soft) bracket/bushing. To truly resolve the issue, you will need more solid motor/trans mounts.

My first gen Barton actually made the 2 - 3 WORSE. My two post cleaned it up pretty effectively. But I also added a Steeda Tri Ax at the same time too...

I will 2nd/3rd motor mounts. That is if the issue is "blocking" and not "grinding"

I've only had this issue downshifting into 3rd at high rpms.

If you are leaning into the shifter at all.. gripping it hard.. you can have this issue.

I learned how to shift quickly with out "leaning" on the shifter.. only pressure is guiding it into the gate.

Since ive learned to do this, I never miss a gear and dont get blocked out. A lot of people dont realize they are putting pressure on the shifter or leaning into it.. pushing left or right.. as they are driving. Especially when your heart is racing and you are trying to slam through the gears.

Glad that works for you but, not all of us try to slam through gears and still have issues.

I have the MGW shifter installed and it solved this problem for me. 2nd to 3rd is no issue anymore.

Like the rest I had similar issues with the stock shifter. After seeing the MGW vids I was sold, I noticed very little additional NVH after install. And the operation is flawless, clean crisp shifts everytime, it's the best money I have spent on this car to date.

A MT82 gearblock on downshift is unrelated, those are a result of the Manual Transmission Fluid that is in your vehicle not providing enough friction to spin the synchro's up to speed... Good Luck Sir.

Did you guys ever try a simple bushing from energy suspension? I tried it out after a few recommendations and I must say that I am impressed. I couldn't believe how soft and fragile the stock bushing were. The install is simple, cost is cheap, and it work with no extra NVH. Shifting is much more crisp and it cleaned up the slop nicely. I don't know how long this will last but it's been doing wonders for the last 3 months. Definitely worth a try

Hi HW_FTW,

As per your Owner’s Guide (3rd Printing):

For the 5.0L V8, shift according to the following chart:

Upshifts when accelerating (recommended for best fuel economy)
Shift from:
1 - 2 17 mph (27 km/h)
2 - 3 25 mph (40 km/h)
3 - 4 40 mph (64 km/h)
4 - 5 45 mph (72 km/h)
5 - 6 50 mph (80 km/h)

If this is roughly how you’re shifting and are having concerns, please visit your Ford dealer for diagnosis. Let me know the outcome.

So people who shift above 3/4K rpm are just SOL?
