Depends of where the leak is. If it's a seal they have some additives that can swell up and restore an old dried out seal which "might" fix the front seals or rear seals from leaking.
If it's from the transmission pan you might be able to "slightly" tighten the pan bolts and stop a leak if it's "small". Bolts are small and you don't want to overtighten and maybe bend the pan or worse break one off in the transmission.
Be careful.
Yes! I used it in my 98 S420 MBZ. No Worries!
If a 1980 Pinto c3 transmission leaks from the front, adding stop lead fluid might help. This can be obtained from retail auto part stores.
Generally, no. However. Sometimes the transmission "stop leak" products may allow you to get just a little more service out of a transmission, depending on the type of leak. Most transmission leaks are internal, and cause shifting problems, primarily slipping. When a transmission leaks internally, the hydraulic pressure is reduced and clutches do not properly engage. Stop leak formulas can reduce those problems and at least temporarily, restore most of the internal hydraulic pressure; but the transmission will not last long. In the process of reducing the leak, the internal seals are softened, causing them to wear out quickly. If your transmission is experiencing leaking to the outside through a seal, the results are less promising. External seals, those which prevent fluid from escaping to the outside of the transmission, fail quickly when you use a stop leak formula, and they do not usually result in leak reduction. External seal leaks are usually caused by a split or crack in the seal and stop leak formulas do not help with that. If the leak is caused by a loose or poorly fitting gasket, stop leak formulas do not help at all.
Transmission stop leak products are primarily designed for automatic transmissions, where they can help seal small leaks caused by worn seals or gaskets. While some products may claim to work on manual transmissions, they are generally not recommended for them, as manual transmissions have different lubrication and sealing requirements. Using a stop leak in a manual transmission could potentially cause more harm than good, leading to performance issues or further leaks. It's best to address manual transmission leaks with appropriate repairs or replacements.
Any stop leak additive is always a bad idea. If you do add it, make sure the fluid level is correct when done.
It needs a transmission oil and filter change or a transmission additive to make the gears not stick so it shifts easier. Or could need both if its an older transmission. You can buy the additive at Walmart or any auto parts store.
no.
To add transmission additive to a 2004 GMC Yukon, locate the transmission dipstick tube under the hood. Remove the dipstick, use a funnel, and pour the additive directly into the tube. Ensure the vehicle is on a level surface and the engine is running for better flow. After adding, check the transmission fluid level to ensure it’s within the recommended range.
The front transmission line leaks, how do I replace it?
yes its called JBWeld
on the ground, if it tranny leaks
Try first with Trans-X, transmission additive before go to shop major repairs
