Summit Racing Transmission Jack

It sounds like a loose plug allowed the hydraulic fluid inside the jack to be pushed out rather than support the load placed on it. Is there any way you can add fluid back through the plug hole it came from originally?

Summit is one of the best around as far as customer service goes. A quick call and I guarantee they'll either talk you through what you need to do to get it to work, or have a new one on its way to you by the end of the conversation.

How about a jack that does the same thing for less than $50?


I built an adapter frame to turn a floor jack into a transmission jack. I didn’t have any fancy metal working tools, so I used a jigsaw, circular saw and a 7 1/4" diameter abrasive metal cut off blade for the circular saw . If you are interested, send me your email address and I will email you the pictures. The 8MB+ zip file is too big to pass through Stangnet’s email gateway.

All the pieces came from Home Depot, including the metal cut off blade. There are 2x4’s, & 2x6's for the wood. You will need some 1 5/8" & 3" deck screws to fasten it together, along with some 2" angle iron. There is a piece of 7/16" threaded rod the the transmission mount pivots on. That allows you to tilt the transmission to aid aligning it up into place. I would recommend that you use some 3/4" plywood to brace the 2x6 mounts that fit the transmission curvature. I accidentally knocked off one of the transmission support upright corners and need to brace it. Oddly enough, the 2x6 will split and crack along the grain of the wood, and that is exactly what happened to me. Make a pair of cardboard templates to fit the transmission curvature and it will fit better and be easier to cut to the right shape. If you need specific dimensions, email me back and I will send them to you

The outrigger wheels can be an obstacle if you don't have the jackstands as close to the front wheel ball joints as possible. There is a 5/16” bolt on each side of the outrigger rails that bolts the fore & aft rails to the jack frame. It doesn't show in any of the pictures, but it is a must have item. It is about 6” back from the ½” hole for the axle where the jack wheels used to mount. With the outrigger setup, you remove the front jack wheels and use the axle to bolt down the fore & aft outrigger rails. They do add a lot of stability to the whole thing, since the transmission is pretty high up when you have it in position to stab back into the bellhousing.

Word: Summit's tools are the same cheap Chinese garbage that Harbor Freight sells. I made the mistake of buying a HF floor jack one time. I took it home and it wouldn't lift the car. I stood on the pad and it wouldn't even lift me. I took it back and the manager said "Yeah, those things almost never work" and gave me my money back. WTH?

I like that home brew transmission jack.

My question is, how do you get the car four feet in the air to get that thing under it with the transmission sitting in it? Cinder blocks? Cedar rounds? Block and tackle attached to a tree limb and a chain under the front fenders?

Haha that is a good point, last trans swap I did I had the front end up on ramps and the rear on the ground because I hate having the car up high, there was certainly zero room for any sort of trans jack.

The aluminum dust pan I got from them works. Everything else has been a smoking pile of excrement that either got returned or S-canned.

Harbor Freight is your friend when it comes to stuff like jack stands. I have 4 tall SUV style jackstands that I got on sale which are perfect for transmission swaps. I get 22"-24" of height which works out OK to get the trans out from under the car.
