BF2S Forums Any Mechanics here?

if you still have issues after it's checked, start a new thread. we'll be sure to help as much as we can.
good luck!

I edited my post w/ more details GS, hope that helps.  Most of it is replacement of the cable, but it does reference adjustment.  Even if you have to replace the cable, that's a heck of a lot cheaper than a transmission.  My car's accelerator started taking more force to push and it would not want to shift like you mentioned and also revved higher.

Oh you could also try taking it to an AutoZone shop and they'll hook the car up to their code sensor machine which may determine what this issue is.  Then again it may not, but it's free so worth a shot.

before you do anything, get your catalytic converter checked, that would explain the hissing, the fact it's getting worse, the funny shifting, and lack of power, and a 4000 rpm max rev. it stems from the fact that exhaust cannot get past the cat and prevents the engine from filling the cylinders with fresh air and fuel. and yes, i am a mechanic.

um, i'd help if I had some more info. What exactly happens? does it rev up? does it click? does it creak? any noise at all, or just won't change gear, feels like you're revving pointlessly?

I hear a hissing sound when I rev it and its stops hissing when it finally decides to change gear.


fluid levels are up.  Thats all I know how to check really.

vacuum hose, unless you have a turbo and not realize it

check your spark plugs/plug wires, check the air filter (probably not it but hey its a good time to check right?)

I can without a doubt say it is NOT the EPA's catalytic converter.  It's just a worthless part of the exhaust system.  It has nothing to do with engine or transmission function.

Do you even know what a catalytic converter does?
Okay, maybe you do. But you do know what the importance of the exhaust system is?

I can say without a doubt that it could very well be the catalytic converter, and no they aren't worthless, we wouldn't have clean cars today without them. I've seen a choked cat cause an engine to not run, and a 460 ford engine fail to reach 25 mph. They can be problematic, and judging from the miles on the car, it's a good possibility. Unless you have a check engine light on, hooking up and reading codes will do no good, as unless the lioghts on the ECM has found no problem with a sensor. . Is the Overdrive light on? if not, then the transmission ECM has no faults stored in it. you would be wasting your money having codes read that will have nothing to do with you problem. Drive it to an exhaust shop, pay the $20 it'll take to have them test the cat, and then go from there. My money's on the cat. a cat can cause problems and ECMs will not pick them up, as it is a mechanical not an electronic issue.

True, but the engine is running fine, it's the shifting that's the issue for GS.

the mechanic I was working hooked up his machine.  Had two faults, both to do with the sensor for the thermostat.  something to do with reading the radiator at too low a temp. thats when we did maintenance on that sensor and hose.  On my way home, the radiator read and the check engine light turned off.  But the problems that I was begining to have during the week just started getting worse as I drove.

I am an ASE certified mechanic.

I don't think your transmission, a 4T-60E, uses a throttle cable. 

off hand I don't recall if your transmission has a vacuum modulator, if it does, and it's disconnected, that could be the source of problem and your hissing noise.  check for a hard plastic/metal vacuum line with rubber hoses at each end going from the top of your throttle body, down the front facing part of your engine, and into a gold or silver colored metal, round thing on the side of the transmission.  if it's there make sure it's plugged  in and make sure there are no leaks. 

jarhedch's suggestion of a bad catalytic converter is a possibility, especially if you were having a coolant sensor malfunction, it can cause a permanant rich running condition that can burn up a cat and induce excessive back pressure.  but generally on your generation of car that would cause a check engine light to illuminate.

beyond that, I'd check your fluid level and condition, make sure it is bright red or pink color and doesn't smell burned.

good luck.

sounds about right, the problem you had causing the light to come on was fixed, the ECM picked up on that, and turned the light off. as far as the ECM cares, everything is working fine. which is why you have no light on. your problem stems from a mechanical issue that will not be picked up by the ECM.

how much is this cat converter fix cost?


this was the right place to get info from.
