It also has the second lowest reverse, and double overdrive- which is really nice for freeway cruising. Common mistakes when diagnosing the P0735 code A lot of times, all a mechanic needs to do is address internal transmission failures as this is responsible for the P0735 code more often than not. A more specific one, though, would be if you notice that the transmission is shifting incorrectly. Either case would indicate that the components responsible for automatically doing this for you are experiencing some type of problem. Racers will probably never leave it, for the previous good reasons, and it is easy to find another core if you break one. Sorry not a very good answer from a mechanic but?? Do you just have code P0732 questions and need some answers about Gear Ratio Error in 2nd? Transmission Swap Comparisons If you are considering a transmission swap the following comparison information can be very helpful in your decision making. If you have Microsoft Excel or Open Office, I can email you a spreadsheet that has really handy calculators to help you see how different gear ratio combinations will work for you.
The solenoid pack is mounted directly to the valve body; its connector protrudes from a hole on the left side of the transmission. Easiest is not always best! You could end up with an overheated transmission or otherwise needing to replace yours. No matter what engine you have, these wide ratio changes result in poorer fuel economy, and require the engine to work harder when pulling heavy loads. Gear ratio data was gathered from reliable public data available on the internet. Partly for that reason, in 2012, when Ram started selling a higher-output Cummins diesel truck with 800 lb-ft of torque , they beefed up the torque converter and modified the shift algorithms for durability. First gear is probably a bit too low in most applications- not so bad for a heavy work truck perhaps, but work trucks typically have lower axle ratios anyway. The is the place where the industries best transmission rebuilders work together to help solve the most complex automatic transmission problems.
If you don't see a specific transmission listed it is because I would not recommend using one for practical reasons- such as there is no current way of controlling it in a conversion, or the engine the trans would be in front of is newer and has more power than the transmission is capable of handling, and no parts are available to make it stronger. The 4th to 5th shift is much closer than most transmissions, so the engine does not have to rev as high to survive a big rpm drop that wider overdrive ratios cause. But where its located and what it looks like i have no idea it could even be mounted inside the gearbox. The code is also associated with P0730, P0731, P0732, P0733, P0734, and P0736. Owners pointed to weak spots in the 2007-11 units, particularly the torque converter. You can also with one of our certified mobile mechanics.
One very common symptom would simply be the Check Engine Light coming on. As the internal clutches of a transmission are usually controlled by fluid pressure or a solenoid, a mechanic would check there next. Even if that was better, the spacing is wider than other transmissions, so accelerating would still be more choppy and less efficient than it could be. There are a handful of common reasons the calculation we mentioned above may not match up and thus cause a P0735 code. If your work truck has a 4. No transmission swap worth doing is cheap. This will show them if the gear is actually working or not.
Fourth gear is a joke that Ford played on everyone- it never really gets used unless the control system isn't happy about something, and isn't worth using anyway- 5th is the same as the 4R100 3rd gear and 6th is the same as the 4R100's 4th. If you want to skip general information and read comparisons between some of the best diesel pickup transmissions follow the links below: Gear Ratio Comparisons and General Information: Dependability and the cost for the swap are what most consider first. Remember, the higher the number the lower the gear- which translates to slow speed but the ability to pull or accelerate. During limp mode, the manual valve provides reverse, neutral, and fourth gear. Power increases are a test for the Allison trans as well, so unfortunately if your Cummins is turned up you will need to spend some money on aftermarket transmission parts no matter what. When considering swapping a manual trans in your truck to replace an automatic, or even putting a lift kit and tall tires on your manual trans truck, beware of gear ratio drawbacks.
These codes should be addressed first before proceeding with trying to fix the problems behind P0735. Assume you already have done the Cummins engine conversion- the adapter plate cost is only included in case you have to change yours. If you must tow 25k with your pickup at 70 mph, then consider the not so easy task of stuffing a medium duty truck transmission in your pickup that has 8 gears or more. If the two ratios are similar, a higher axle ratio can be used to idealize the drivetrain efficiency. Service fill is 6—8 quarts. Trans Swap Cost Comparisons Choose Wisely! I figure if a guy is going to go to the trouble to make the best truck out there, he should probably have the best type of transfer case too. If it had a lower reverse, tall tires or higher axle ratios could be utilized to make it a good combination.
Maybe the next trans Ford builds will be better. Part of the process involved is calculating engine speed against the transmission speed sensor to assess the torque converter slip and gear ratio. Not necessarily so with racing- as the early control systems are limited to converter lockup in 5th and 6th gears only- no 3rd lockup is available without tuning tricks that may or may not work. They all use three planetary gearsets, three driving clutches, three holding clutches, and an overrunning clutch. The drawbacks to swapping this transmission into a Ford or Dodge pickup is the expense. You may also even be able to feel the transmission slipping. Unfortunately the spacing between 1st, 2nd, and 3rd gears is a bit too close for it to be ideal, so it's not much different than the 4R100 as far as gearing goes.
Unless you are pulling really heavy loads, the extra gear really doesn't help much because it only helps get you going a little better from a stop. Custom adapter and flex plates, driveshaft modifications, control system and tuning, and getting the transfer case you want connected if your truck is a 4x4 all adds up to a very significant investment. All the transmissions listed are high level builds, and core charges are added to the price. The converter is located between the transmission and the engine. If you are building serious power under the hood of an older truck you should add more for a transfer case upgrade swap too. Need help with a P0735 code? Additional comments for consideration regarding the P0735 code Even after repairs and after the system has been retested, use a short test-drive to ensure shifting works and to see if P0735 or other associated codes return.
