One of the best digital inclinometers you can buy without spending a lot more $$$. I validated it's accuracy against one we use at work that cost 5K that we use for measuring propeller shaft angles on marine vessels and it was spot on for accuracy (+/-) .1°
Thanks, tmcolegr. I will order one from Amazon now. I appreciate your information.
If I read the TSB correctly, the driveshaft angle should be between 5 and 6 degrees after shimming? I know yours is 5.4. but just wanted to make sure I am understanding the TSB correctly. You said yours was at 6 degrees before the TSB and was 5.4 after. Theoretically, your truck was within the the spec for driveshaft angle (although at the upper limit of 6 degrees). If you had shudder at 6 degrees, maybe Ford should change the angle they are shooting for. I don't know what mine was before or after for that matter. When I get my gage, I will be able to tell.
I couldn’t see anything around the wheels or drivetrain. Probably not related to the other issues in this thread but thought I’d throw my experience in in case others have had similar. Will mention to dealer when I next go in but not holding my breath for a solution
The dealer said my angle was 5.4 degrees before I got them to do the TSB. They had been insisting it was just the "herky jerky" 10 speed and that it was operating as designed. I complained to the sales manager and they agreed to do the TSB "to make me happy". The result was 4.9 degrees and all it did was shift the shudder to a different speed range. They agree there is an issue but unless Ford finds (and more importantly, will pay for) the repair, they won't do anything else.
Yes, technically it was within the range of 5* to 6*. However, the dealer was willing to install the .5* shim to get the pinion angle as close as possible to the desired 5.25* which is optimal.
What is disappointing is I spoke with the service manager and technician on the phone and went through the TSB. I believed they understood it. I have my own digital angle gauge similar to yours and will continue to verify the work until the numbers are in spec.
Now that I have 1500km on mine I still can’t decide what the issue is. A couple times when it was near freezing out. the first minute or so of slow speed driving coming out of my neighborhood, the shudder was unmistakable, meaning even the passenger noticed it.
I think it is something other than the driveshaft angle causing it. On my truck, it is always there, but sometimes a lot worse than other times. I would think if it were the driveshaft angle it would be consistent.
Sometimes I’ve noticed the same erratic behavior. Cold weather especially, start up and go it runs like crap. Let it warm up a bit and it’s fine. The TSB 2239 made a difference though.
Exactly
Mine runs and shifts a lot better after it has been driven awhile. When cold, it acts like it doesn't know when to shift and is pretty jerky. After it warms up, it shifts better. I don't know that getting it warm is what improves it or maybe driving it awhile distributes fluids where there need to be. I had the dealer reflash the software when I took it in to have the first oil change. After that reflash it shifted a lot better initially. Now it seems to be going back toward the more harsh shifts. I guess time will tell. If the shuddering would go away and if the tranny would shift better, I would love this truck.
I finally got it in to the dealer on Saturday to have them go change the oil, check the transmission level. The tech reported the transmission fluid level was 3/4 of a quart low and topped it off. He also reported no visible signs of leaks or seepage and at 4200 miles that can only mean Ford underfilled it just like many of the Mustang owners have reported. Mine has a Nov 2019 build date.
