Software or Sensor – Most modern vehicles have software that controls when and how hard the transmission will shift. It is one of the most neglected maintenance items on a vehicle. Just like all fluids in a vehicle, transmission fluid breaks down with the passage of time.

If you can’t remember the last time that you changed the changed the fluid see number 2 directly below.īurnt/Old fluid– If the transmission fluid is burnt smelling, but otherwise looks full you still may have stumbled upon the problem. If the fluid is low, and you haven’t driven the vehicle with the transmission slipping too much, you may have gotten off lucky. The dipstick should say something along the lines of “full-hot”. Most manufacturers want you to check the fluid when the vehicle is at normal operating temperature. Low or No fluid– The first thing that you’d want to look at is the transmission fluid level. Below you will find a list to help you diagnose the issue. It is VITAL that you get your vehicle to safety right away. Typically, a transmission will first begin slipping when it is under a heavy load, so you’ll generally feel the engine rev higher even though you haven’t pushed the gas pedal any harder.

You may also be interested in how to know if your transmission is slipping. Often, low transmission fluid is the cause. Make sure that your fluid is at the proper level. This also is true for the smaller transmission, 2004R.
If it’s not the TV cable, just follow the normal diagnostic Cycle for any transmission. If you do have that feeling, but are pretty sure that the transmission should be fine try adjusting the TV cable. If it is out of adjustment the shift pressure will be down and may be hindering the ability for the transmission to shift. A TV cable that is out of adjustment can give a very similar feeling. Or at least it gives the feeling of slipping. With the 700R4 transmission specifically, it is possible that the transmission is fine yet still slipping. My thinking is that I should just go ahead and drop the pan, replace transmission filter, pan gasket, and TV cable all in one go.It can be really scary with any transmission slipping. Compounding issues clog transmission filter with debris, though I am praying not a fatal amount. Improper pressure leads to hard shifts, stretched TV cableģ). Transmission rebuilt, they put in too much fluidĢ). Don't blame me I bought a 38 year old truck barely knowing how to change oil so I am proud of how far I have come.ġ). While on the transmission rabbit hole, I discovered transmissions have filters. I did double and triple check the geometry of the TV cable bracket, seeing as how the carb is aftermarket.
I have a new one coming in that I will replace, but for now the adjustment doesn't seem to do much. Had trouble adjusting it it seems like it has been stretched. Fixed that, problem went away for about 2 months, then returned. Found way too much fluid in there (about a half gallon too much, for which I will point the finger at the transmission shop that recently rebuilt it). Sometimes, especially when cold, the transmission shifts hard, feels like it shifts too early, sometimes when accelerating I get to about 3rd gear then it won't shift before I hear a pop and it downshifts. 350 crate (14,000 miles) 1406 Edelbrock carb, 700r4 transmission (7,000 miles since rebuilt).
