Instant Shudder Fixx Automatic Transmission Fluid Additive 12-Pack [20-UP]

When a torque converter shudder call comes in and the diagnosis points to fluid chemistry rather than worn friction material, having the right additive on hand closes the job the same day. This case packs twelve individual units of instant shudder fixx automatic transmission additive into a single order, giving a shop or counter operation a working supply without the delay of reordering unit by unit.

Each of the twelve doses is intended for a single automatic transmission service where shudder during light throttle application or lock-up engagement is the primary complaint. The additive works at the fluid level to address the friction-chemistry mismatch that causes that characteristic vibration, so the technician does not need to pull the unit apart to treat the symptom when the root cause is in the fluid.

The case contains nothing beyond the twelve additive units. There are no friction discs, no steels, no filter, no gaskets, and no bands. If the inspection points to worn clutch packs or a damaged converter, this product does not cover those repairs and the correct hard-part kit should be sourced separately. Confirm the diagnosis is fluid-related shudder before placing the order.

Every order is assembled here by REMCO, pulling each of the twelve units individually and verifying the count against the packing list that ships inside the box. REMCO has worked exclusively in automatic transmissions since 1991, and that single-line focus is why the case arrives complete and ready for the counter without surprises. Total shipping weight is 1.95 lb for the full twelve-unit case.

• Twelve individual doses of instant shudder fixx in one case give a shop or reseller a ready supply for the most common torque converter shudder complaints without reordering constantly.
• This case does NOT include friction discs, steel plates, filter, bands, or any hard parts; it is a fluid additive treatment only, so verify the repair call before ordering.
• Shudder during light throttle or converter lock-up is often a fluid-chemistry issue, not a mechanical failure; this additive targets that specific symptom at the fluid level rather than requiring disassembly.
• Contents: 12 units of instant shudder fixx automatic transmission fluid additive, no other components; case ships at 1.95 lb total and each unit is sized for a single service application.
• Before ordering, confirm the vehicle is experiencing torque converter shudder linked to fluid condition and that no hard-part replacement is needed; this additive does not substitute for mechanical repair.
