torque converter Hello, what are the symptoms of a torque converter? And what can cause it to fail? Thank for your feedback |
Re: torque converter what are the symptoms of a torque converter? But I'm guessing you're REALLY asking, what are the symptoms of a torque converter FAILURE. In which case, usually it's strange noises, or metal in the fluid. Or in the case of a lockup one, failure to lock up. And what can cause it to fail? |
Re: torque converter ok, then I am not on this problem, in fact, I have a problem on downshifting on 2-1, with a little clunking or bump or litle jump(sorry for the term I am french), only in D, in OD no problem ! For example when I arrive at a stop, when I brake gently => problem detected and if I brake hard, it is not detected.... I have changed the mount trans, yokes are good...check the tv cable, flush fluid trans........ where could this come from? Gouvernor ? |
Re: torque converter when in D the over run clutch is engaged and a little clunking or bump when downshifting is normal |

Re: torque converter Ah ok "the over run clutch" is engaged only on D and not in OD ? Yes newer transmissions had more refined valve and fluid passage control of things, improving all of that. The 4L60E and 4L65E use the same clutch arrangement, and similar refinements continued during its production run as well. |
Re: torque converter ok thank for your detailed feedback ! .. and a new adjustment of the cable TV will not correct this sensation ? I have already done but that never change anything ... with minimal adjustment only because I know, it can be dangerous... for transmission |

Probably not. It's internal to the transmission. A new servo (the thing that applies the band) might help. Get a "Corvette" one. This one for example. There is this kit also, perhaps it can be benefit ? => https://transgo.com/product-details/700-jr-shift-kit/ |
