The torque converter is responsible for transmitting the engine’s torque and power to the transmission.

Transmission Torque Converter Clutch (TCC) Solenoid: DESCRIPTION Positioned between the rear of the engine and the front of the transmission is the torque converter. So I wanted to ask you 2nd gen guys directly to see what your advice would be. If the torque converter clutch solenoid is stuck in the open position, you may notice that your vehicle hops when sitting at a stop, or stalls against brake. And he told me that is a terriable solution because it will ruin rubber seals an create larger problems over times. I also seen where people recommended using tranny dr insta shudder fix. He is $190 to change and fluids, and quoted me $1100 to change the torque converter. I don’t know if the shudder an vibration go hand in hand or not. He said if it’s not addressed it can lead to the filter being clogged, the tranny starved for oil an a transmission rebuild. What Does The TCC Solenoid Do The main function of the toque converter clutch or TCC solenoid is to send pressurized fluid to the torque converter’s clutch allowing it to achieve lock up in 4th gear based on a signal from the engine control module (ECM). That the issue is likely related to the torque converter.Īfter contacting the local transmission expert(to ask him how much he would charge to do a flush an refill) he said it sounds like I am experience torque converter shutter, and that likely I need it replaced. All of the solenoids can be easily checked with an ohm meter. ATF costs between 6 and 10 per quart and you will need 3 to 5 quarts. If you choose to replace this fluid with new fluid the approximate cost is 20 to 50. The two most likely to fail are the transmission pressure control solenoid and the torque converter solenoid. Normally the transmission fluid that is drained from the pan when replacing a solenoid or solenoid pack is reused. At first glance it appeared to be the shudder that is common with Tacoma’s.Ībout 400 miles ago my truck started to shudder then followed by a fast vibration(felt like rumble strips but no as intense) it last for about 3 seconds then goes away.Īfter doing some research on here I have found that a complete flush of the tranny an refill should take care of it. 1) Solenoid failure: The 4R55 is an electronic transmission and as such, it contains a few solenoids. My truck is an 07 prerunner, automatic with a V6.Ībout 5k miles ago my truck developed a shudder under load between 20-30 mph. I also contacted 2 very highly rated transmission shops locally. Hey everyone, I have been doing a ton of research on here and on google.
