"limp mode"
this limp mode is a bunch of crap. What I want to know is if there is a sensor that says something is wrong.....and puts it in limp mode...........is there a way to bypass that sensor to get the rest of the life out of the tranny. it goes "LIMP" but is there any type of temperary viagra for it????

First, please delete your double post.
There are a lot of sensors that inform the control modules of system status...many of which can cause the programming to go into a limp or baseline mode. Specifically, it sounds like you are speaking of the PCM (powertrain control module)...is the transmission stuck in 2nd gear? You can try disconnecting the battery for a few minutes to reset the computers. If there is a problem though, it will go right back into "limp" mode. Plus this can cause other temporary drivability issues (start - die, rough idle, etc).

There are a whole laundry list of conditions that can cause the TCM to go into limp mode. You may not need any "Viagra", you might just need a new speed sensor, or the connector on the solenoid pack could be loose, dirty or broken.
One thing is for certain; if you keep driving it that way, you'll burn it up. A $35 speed sensor problem can cause a $2200 transmission overhaul problem pretty quickly. The only way to find out is to pull the codes from the computer and find out why the heck it's limping. |
