      @DB Walker sorry for late reply. Does the vehicle continue to drive in 2nd gear? Or it looses gear when you get to the point where you should shift into 3rd? I guess another way to ask this, does it stay in 2nd? Reverse ok? It might be your shift solenoids. Easy to replace without pulling engine. Do you have any engine codes?

    I watched your first video earlier today and I was like yeah I don't think that's going to fix mine.. I believe my problem is that 3-4 accumulator which I don't know if it's possible to change that in the truck.. I think that's the only thing wrong with mine I'm guessing the spring broke or the seal failed? My issue is my trucks downshifting so hard from overdrive that you'd think it's about to break something and I'm driving it around with overdrive off. Thanks for the video! You gotta keep that truck now forever lol.. I did my dodge ram v10 a few years ago I'm never getting rid of it unless that transmission breaks again lol

    • @DrivingIntelligence

      Nice truck, and wow, a V10? nice... with regard to your 3-4 accumulator, you can replace while in truck by removing the valve body and using the special tool I show in my video. It's gonna be messy! The hard downshift is a concern, could be many reasons for this. Does it do this downshifting from any other gears? Stay tuned, my tranny is starting to make me worry again, only slightly. The truck shudders in 4th which tells me it's finally time to get my other transmission rebuilt and installed in this truck. I'll be doing videos on the rebuild.

      based on this comment, I would say you have either a torque converter problem, or a problem with controlling the fluid circuits in your valve body.

      Hi, all the parts I used are in the description with Amazon Links. If you want accumulator springs, you get most of what you need here: Shift Technologies Shift Kit for 4R70W - amzn.to/30jf8RX - I suggest if you do this, you also get these parts: AODE 4R70W Piston Set 1990 and UP - amzn.to/2E3TNAL - these will work with a 4R70W Transmission which is likely what you have in your truck.

    I’m wondering if you can point me in the right direction. I have a 2002 F150 5.4 FX4 that developed a rough shift from 2nd to 3rd at low rpm’s especially when warm but normal at higher rpm’s. It’s at 130,000 Miles. Just recently it began doing this jerk at when accelerating from stops. Like the torque converter is abruptly locking from neutral when I give it gas. Another way of describing it is it is like it is in neutral after holding the brake and when I let go at times it’ feels like I am shifting from neutral to drive. I’ve heard that the 2/3 accumulator is also responsible for “forward engagement”. Could the 2/3 accumulator be responsible for these issues?

    • @DrivingIntelligence
      @DrivingIntelligence  4 месяца назад +2

      If the 2-3 shift accumulator is bad, you won’t get third gear. If it’s leaking, you’ll get a sloppy shift from 2nd to 3rd. Based on what you’re telling me, my assumption is that you have problems with the valve body. There are a multitude of valves in the valve body that impact shift quality. Take a look at this webpage which can help isolate problem areas: www.transmissiondigest.com/critical-wear-areas-vacuum-test-locations-2/

  • @aeylxb3472
    @aeylxb3472 Год назад +3

    I may have an issue with my 2/3 accumulator. The transmission shifts great through out all the gears as I accelerate and also down shift with no issues. But when I slow down to 18 or 19 mph and accelerate again, it seems as though either its accelerating very slowly or in neutral. I have to step off the gas and then apply the gas again slowly for it to pick up speed again as normal. Its the 4r70w transmission in an 05 crown vic. It might be a stupid question but what state are you located in, maybe I can drive to you so you can help me fix this issue and I can pay you because the mechanics around my area don't seem to know what to do or they keep sending me to other places.

    • @DrivingIntelligence
      @DrivingIntelligence  Год назад +1

      Thanks for your comment and considering me to help you get your Crown Vic right... let's start with some basics: 1) do you have any diagnostic trouble codes? 2) have you recently removed the pan and installed fresh fluid and a filter? This could be caused by several issues like a faulty TPS, bad shift solenoids, bad accumulator, leaky separator plate and on and on.

    • @aeylxb3472
      @aeylxb3472 Год назад +1

      @@DrivingIntelligence no, I have not changes the transmission fluid or have any diagnostic codes. I checked those with blue driver obd2 and nothing. Also I'd like to correct myself; it's not the 2-3 accumulator but the 1-2 accumulator most likely because everytime this happens at around 18 mph after breaking to that speed and accelerating again, the engine wines the same way it does at 1st great except it wines faster since at that speed it should already be at 2nd gear. It's as if I had a menual transmission and I didn't shift into 2nd when I was supposed to. So it must be the 1-2 accumulator because only thr 1st gear wines like that. As far as the TPS. Don't think that's the issue since the accelartor peddle is responsive all other times as well as when the transmission hesitates to shift to 2nd gear. It may not shift right away but the engine does respond well to accelerator input. Another thing is, the 1-2 hesitation seem to happen once the engine warms up. Also, at lower accelaration 1st changes to 2nd at around 10 mph and at faster accelaration, 1st changes to 2nd at around 16 mph if that makes any difference. Thank you for replying and I appreciate any input or advice.

      @@aeylxb3472 it sounds like it could be the 1-2 accumulator, and you are in luck. You don't need to remove the valve body to replace that accumulator. The springs or spring in the 1-2 accumulator have been know to fail / break. You could drop your pan, change your filter, fluid and the 1-2 accumulator and associated springs, and see how that works out. By the way, I'm in South Carolina.

      @@DrivingIntelligence Strangely the issue has begun slowly subsiding and then I realized that the only thing that I have done differently was unplug my blue driver OBD2 from the port. So it must have been that, which was causing it since it has always been plugged in. It must've messed with the computer. I spoke to one of the mechanics from Ford service and he told me you are not supposed to leave anything plugged in for prolonged period of time. Another issue I'm having is a humming sound coming from the front end between the 1 and 2 gear while accelerating and only happens if i slow down to around 18 mph. I read that it could be a dirty IAC. Anyways I'm really not sure what the issue is but I will try to figure it out.
