Challenger CLHMHTJ-1200 Hydraulic Transmission Jack - 1,200 lb Air/Hydraulic 2-Stage
Dropping a transmission is one of the most unforgiving jobs in the shop. You need reach, control, and a head plate that actually cooperates with the unit you're pulling. The Challenger CLHMHTJ-1200 transmission jack delivers all three. It's a 1,200 lb capacity, two-stage air/hydraulic transmission jack that lifts fast and lowers with precision - the kind of combination that makes back-to-back transmission jobs feel manageable instead of brutal.
The two-stage design is the real story here. The first stage is 100% air-operated, so you're not pumping your way up from the floor. Connect shop air and the jack rises quickly to working height. Then the second stage hands off to hydraulic for precise, controlled positioning right where you need it. That transition from speed to control is exactly what transmission work demands - and most hydraulic transmission jacks on the market give you one or the other, not both.
Rated No. 1 by professional R&D technicians and made in the U.S.A., the CLHMHTJ-1200 features Gray Manufacturing crafted transmission jack adapters designed for multiple transmission types, heavy-duty acme threaded screws for smooth tilt adjustments, and four quick-ratcheting brackets that make the 11.5" x 11.5" head plate genuinely adaptable. The swivel casters let you maneuver it under the vehicle without wrestling it into position. A nylon speed strap comes included to secure the load before you move.

Installation & Setup
The CLHMHTJ-1200 requires a shop air supply delivering 90-160 PSI (6.2-11 BAR) to power the first-stage lift. Before use, verify your compressor and lines can hold pressure within that range - too low and you won't get full first-stage travel, too high and you're outside the rated operating window.
The jack arrives assembled and ready to roll. No floor anchoring or permanent installation is required. Confirm your bay has adequate ceiling clearance for the 72" maximum lift height before positioning under the vehicle. The 41" x 41" footprint and 4" swivel casters give you solid maneuverability on a flat shop floor - avoid uneven or soft surfaces that could compromise stability during lifting.
Applications
The 72" max lift height makes this jack the right call for trucks, vans, and larger SUVs where standard low-rise jacks simply can't reach working height safely.
The Gray Manufacturing adapters and quick-ratcheting head plate brackets mean you're not re-configuring between every job. Fast swap, fast setup, back on the clock.
Starting at 34-1/2" minimum height, the CLHMHTJ-1200 works comfortably beneath vehicles on a two-post or four-post lift, giving you the vertical range to position precisely without working at floor level.
The hydraulic second stage and multi-axis tilt - 40° forward, 20° rear, 10° side - let you match the transmission angle to the bellhousing before you close the gap. That kind of control cuts reinstall time significantly.

Frequently Asked Questions
What air pressure does the CLHMHTJ-1200 require?
The jack requires shop air in the 90-160 PSI range (6.2-11 BAR). That's well within what most commercial shop compressors deliver. If your supply pressure falls below 90 PSI, you won't get full first-stage lift travel. Make sure your lines and regulators are set before the first use.
What is the maximum lift height, and will it work under vehicles on a lift?
The CLHMHTJ-1200 reaches 72" (182.88 cm) at full extension and starts at a minimum of 34-1/2" (87.63 cm). That starting height is specifically useful when the vehicle is already raised on a two-post or four-post lift, giving you a practical working range for transmission removal without crouching at floor level.
How does the two-stage air/hydraulic design work?
The first stage is fully air-operated - connect your shop air and the jack rises quickly without manual pumping. Once you're near working height, the second stage switches to hydraulic power, giving you slower, more precise control for final positioning under the bellhousing. You get speed where it doesn't matter and precision where it does.
Does the head plate tilt, and how much?
Yes. The head plate tilts 40° forward, 20° rear, and 10° side. That range lets you match the transmission angle to the vehicle's mating surface during reinstallation, which is where a lot of time gets lost if your jack can't flex. Adjustments are made via the acme threaded screws on the four quick-ratcheting brackets.
What adapters are included and what transmissions do they fit?
The jack includes Gray Manufacturing crafted transmission jack adapters designed for multiple transmission types. Gray Manufacturing is a well-known name in professional-grade adapter tooling. For a confirmed list of specific transmission fitments, call us at (855) 498-2147 and we'll walk through compatibility with your vehicle lineup.
Is this jack made in the USA?
Yes. The Challenger CLHMHTJ-1200 is made in the U.S.A. and was rated No. 1 by professional R&D technicians. Challenger Lifts manufactures out of the United States, and that domestic production standard is reflected in the build quality of the acme threaded screws, casters, and head plate components.
What does shipping look like, and is there a freight charge?
Shipping is free to the lower 48 states. The jack ships at 125 lbs., so it moves via freight carrier. If you need a specific delivery window, liftgate service, or residential delivery, contact us at (855) 498-2147 before placing your order so we can confirm the details and any applicable accessorial charges upfront.
What does the warranty cover and for how long?
The CLHMHTJ-1200 is covered under Challenger Lifts' limited warranty: 1 year on labor, 1 year on functional parts, and 1 year on structural parts for the original purchaser. The warranty requires proper installation and use per Challenger's specifications. Accessories and replacement parts are covered for 90 days. Warranty registration may be required after purchase - refer to the documentation included with the unit.
