torque converter problems?

gsxr750 · 12-04-2006, 02:54 PM

so i just got off the phone and the shop talked to some people and think the tranny converter is shot, but you need to pulll it to measure it and see what one you have, but anyways the tranny shop said that in the early 90's they used a 2 part shifting mechinism with a checkvalve and they tend to get "clogged" which is why in low range itll run like a bat outta hell and when you put it in high it wont "have any go power" they said even know the truck just had all this tune up work done to it, it kept fowling out plugs and sensors cause of the restriction, which is why it wouldnt want to start easy, so before i pay another shop to do more work and pull my tranny, do you guys think this may be it????????????????

Proper grammar goes a long way in describing problems to people. Can you repeat that in english?

my trucks sluggish as hell and just been getting worse and worse over the summer, now it wont go up hills, if i put it in low range itll have power, if i put it inhigh range it wont even spin the tires in dirt. the basic tune up things have been all done and it keeps fouling out the plugs cause of the restriction due to the torque converter being shot when u test drive it, it will have a restriction on the motor so it fouls out the plugs , anyone hear of a torque converter going bad?

Yup, you can blow a TC and that will call for a tranny rebuild.

Pull the pan (tranny) and take a look. See what, if any debris is in the pan, what color, how much, etc.

Are you sure that the tranny is shifting correctly and then it's starting in 1st gear, etc. ?

low range?? high range?? What?

How does a torque converter have ANYTHING to do with fouling plugs???

You've got more than one issue and they are unrelated....

The fouling plugs could be a LOT of issues, but rich condition, detonation, oil in the intake are the first things that come to mind. I've never heard of a TC blowing up on such a low power application as a 3vze or 22re or 5vzfe for that matter.... Id solve the fouling plugs issue first personally.

Don't sound like no torque converter problem that I've ever seem. If the TC is bad in high range then it still gonna be bad in low range. I believe that you've got a secondary ignition problem that's causing the lack of power.

No, not at all. It sounds like you might have an open in a solenoid circuit and its trying to start off in too high of a gear. You have 2 solenoids which give you your four shifts. A combo of the 2 solenoids being on/off is what does it. It require both on to get 1st gear, all off to get 4th or OD. If you are missing one, you will get a 1 and a 4th gear, while the opposite solenoid working wil start you out in 2nd and shift to 3rd only. I'd check codes. I suspect someone either doesnt understand the tranny or does and s trying to "kink ya"

What tells the solenoids to turn on and off, i have a 85 auto 22re that will only shift manually....it starts in high if you put it in drive and that is all it does, all the gear are there if you shift manually.

Tranny ECU, its seperate in the 85's. There is input to the ECU (speed etc) and output controls solenoids.
