Solving Transmission Problems
Transmissions
It doesn’t matter if you have a manual or automatic transmission; they both do the same thing. Transmissions, or gearboxes depending on where you’re from, provide a reverse gear and mechanical advantage to the engine’s power output. Your engine works best within a given RPM range. Go above that range, and the engine might fly apart violently. At RPMs below the engine’s peak torque output, the engine isn’t working as efficiently as it could. The transmission helps keep the engine in a good operating range for maximum power and efficiency. I’m going to divide this article into two sections: automatic transmissions and manual transmissions. We’ll start with manual transmissions.

Eric – I live in the oven = Arizona and would like to hear your thoughts on whether or not adding a separate trans cooler is worth the extra $$$ ? The lines on my 1992 f150 go through the radiator. I’m considering adding a separate cooler with fan attached which will go in front of the radiator. Thoughts? Thanks.

I do appreciate that this post pointed out that it is important for us to have our transmission repaired by professionals. In doing so, we can prevent further damage. Assuming that I need to have my transmission repaired, I will look into hiring a certified professional.

I have a 97 Honda accord 4 cylinder and I recently got code p0715 and I changed the sensor. After changing the sensor the code came back and i changed it again. Now my car is making a whirling sound and its still having the high rpm low speed issue in addition to the code p0715. What could be the issue? What am i missing?

consider replacing your transmission as a unit yourself if you find that you have an internal transmission problem you can’t fix. Especially with automatic transmissions, this would be a good course to follow. Another option to consider is removing your failed transmission and taking it to a shop that can rebuild it for you. At least you’ll be able to save on the removal and replacement of the transmission. (Drop-in a used) Be sure you find the correct transmission, the right fluid, and understand the TCU. Learn the Transmission that is installed. Re set the TCM/U that you have. re-check the rest of the modules that affect the computerized operation of the car, too. — Battery disconnect, low fluid, and pressure change can destroy a transmission that you have 30 to 90 day warranty for, if that. My A604 is non functional likely for this reason. Presented starter type problem, cranked after the computer reset third time, you go off.. and after it sat, same thing. You can go through replacing three and more sensors, and three on a transmission, and checking vacuum.. that might resolve a bigger problem later. Keep the fluid filled. Instead you might see white smoke billow from a relief opening after a hard clunk, then no gears will engage. That might be serviceable, or not. At 127 thousand miles, this car might get a drop-in, and be resold to a desperate person that needs a car. A car that might last longer, or not. “For Sale in Georgia”
