11 best automotive performance torque converters

Automotive performance torque converters are components in a vehicle's automatic transmission system. They play a crucial role in transferring power from the engine to the transmission, allowing for efficient and smooth operation. Here are key aspects related to performance torque converters:

  1. Functionality: Torque converters are fluid couplings that connect the engine's crankshaft to the transmission. They allow the engine to continue running while the vehicle is stationary and smoothly transmit power to the transmission as the vehicle accelerates.

  2. Performance Upgrades: Performance torque converters are designed to enhance the overall efficiency and performance of the transmission system. They are often chosen by enthusiasts and drivers seeking improved acceleration, responsiveness, and overall driving experience.

  3. Increased Stall Speed: One common feature of performance torque converters is an increased stall speed. Stall speed refers to the engine speed at which the torque converter fully engages. A higher stall speed can result in quicker acceleration and improved performance in certain driving conditions.

  4. Customization for Engine Mods: Enthusiasts who have modified their engines for increased power and performance may choose a performance torque converter that is specifically matched to their engine's characteristics. This customization helps optimize the power transfer and overall drivetrain performance.

  5. Lock-Up Clutch: Some performance torque converters come equipped with a lock-up clutch. This feature allows the converter to mechanically lock, reducing slippage and improving overall efficiency, especially at cruising speeds.

  6. Construction Materials: Performance torque converters may use high-quality materials in their construction, such as billet steel or aluminum. These materials enhance durability and heat dissipation, making them suitable for high-performance applications.

  7. Compatibility: It's crucial to ensure that a performance torque converter is compatible with the specific make and model of the vehicle.Different vehicles have varying transmission specifications, and choosing a torque converter that matches these specifications is essential for optimal performance.

  8. Installation Considerations: Upgrading to a performance torque converter may require professional installation due to the precision and expertise needed to ensure proper alignment and function within the transmission system.

In summary, automotive performance torque converters are aftermarket components designed to improve the efficiency and responsiveness of a vehicle's transmission system. They are often chosen by performance enthusiasts seeking enhanced acceleration and a more engaging driving experience. Compatibility with the vehicle and professional installation are essential considerations when opting for a performance torque converter.

User questions & answers

Question: Does this fit a 1970 olds cutlass supreme
Answer: Any member of this family, 2,4, 8 port can be hooked up to a stereo receiver. This is an un-powered mechanical switch that does not modify the signal in any way. You can use it for just audio, just video, or both. You can use it to send several signal sources to one input of the receiver or vice versa - one output to a variety of other devices (recorders, displays, etc.) Either way, you can only connect one device at a time to one other. One input at a time to the receiver, or the receiver to ONE downstream device at a time. There is no signal processing whatever, so the electrons can go either way. Note that this is intended as a line-level device, so you may hear noise pickup if using it at magnetic phono signal levels (or if you have a loose connection), and you may damage the device if you use this for speaker switching due to high currents when playing speakers loudly. You will probably not burn switch contacts if you turn off the volume when changing a speaker selection, but who remembers to bother to do that especially when you are trying to compare how two sets of speakers sound?
Question: Will this fit my 2004 trailblazer 4.2 inline 6 ? I lost my bolts jus got difrent motor in
Answer: You cannot send one signal to 8 outputs AT THE SAME TIME, but you should be able to send the one signal to any ONE of the 8 ports of your choosing. This is only a mechanical switch and the electrons do not know or care which way they are going so long as there is a path to follow. My use is to have two of these stacked together and have one as an input switcher and the other as an output switcher. I do not need hi-def, and my older sources don't have HDMI. I am inputting from CD, DVD, TV, LP, Cassette, R2R tape, Game box, and even VCR, then outputting to any one of the following: TV, DVD-R, audio amp, headphones, video processor OR (not AND) PC. My only cautions are to be gentle but firm when making connections - this is not a commercial performance-grade product- and for the same reason, turn off any inputs you do not currently need, to reduce signal bleed-through from other sources. If this is too much of a nuisance, you can easily spend hundreds of dollars for a device that will do exactly the same thing as this unit, but will stand up to frequent road trips and on-stage abuse.
Question: Do these fit 67 impala ? 350 goodwrench with turbo
Answer: This device has RCA output jacks. So ideally you would need to have a small amplifier that plugs into this device and has a headphone jack (like a Lepai or similar device).
Question: Are they7/16 fine thread pitch
Answer: I suggest you need a hdmi switch 5 port in 1 port out to one tv,https://www.amazon.com/gp/product/B01FXALWYY

User questions & answers

Question: Will this fit a c4 transmission
Answer: It did that for me. I believe the TV hardware does the appropriate scaling, not the converter adapter. The converter just makes the signal compatible with an HDMI input.
Question: Will this fit a 700R
Answer: No. This is only to allow RCA-style output to be converted for HDMI input in devices that don't support HDMI natively.

User questions & answers

Question: Will this work for 02 5.3 vortec to 700r
Answer: Yes. It probably will work. You should hook it up so your old RCA device is feeding its signal to the converter and then to the TV, not the other way around. Depending on the old RCA-cabled device, the video resolution on the TV may be lower.

Painless

Based on 15 reviews Check latest price

Product description

This TH700R4 Transmission Torque Convertor Lock-Up Kit takes all the guesswork out of controlling the lock-up function on your TH700R4 overdrive transmission. This kit will work with both carbureted and fuel injected engines and saves you from having to buy any separate, expensive computer-controlled equipment. A provided vacuum controlled switch and 4th gear pressure switch controls the torque converter lock up solenoid. Kit comes with everything needed to complete the installation and fits any GM TH700R4 transmission. This kit includes: Vacuum switch, 4th gear pressure switch, brake switch, torque converter lock-up solenoid, wire harness, transmission pan gasket and mounting hardware. NOTE: The GM TH700R4 transmissions were offered in GM cars and trucks from 1981 thru 1993. This transmission kept its designation of TH700R4 until 1990, when GM renamed them the 4L60. The 1990 thru 1993 model years "4L60" used a round 5 pin connector and no longer used the square weatherpack connector. Painless part number 60109 is provided with the early square weatherpack connector.

    Question: What is the spline count
    Answer: As you described it, NO. This thing only has ONE HDMI OUTput. THREE HDMI INputs. But only ONE output for video signal. But there IS a way to do what you want. Take the single HDMI OUT, take it to an HDMI to VGA converter to get the video signal to the projector. Then take the TOSLINK/DA out to get audio to the soundbar. MOST soundbars can handle the lightpipe signal. If yours does not, there are several adapters here that can convert the DAO to RCA.
