Q & A

What's in the Box

Our rebuilt Saginaw 3-speed (1-1/8" - 10 spline) has new bearings, seals, snap rings, and gaskets.  All are stock ratios with unaltered gears in use.

Transmission shipping case required with each order. Case cost is refunded when returned, less UPS ARS.

SPEEDWAY TECH TIP: If your engine is solid mounted, don't use anything more than a rubber tranny mount. That can save your tranny if you hit the wall.

                        Avoid messy transmission leaks with this tailshaft plug. Fits standard GM transmissions such as 3 speed / 4 speed manual or TH350 auto using 1-3/16" x 27 spline.
Lubrication Engineers SAE 140 Weight Gear Oil, 1 Gallon
(Part #91044140)

Whether you're running a stock flattie and rearend or hopped-up overhead and quick change, you need to run a good gear lube. Remember that your rearend was designed fifty plus years ago and needs all the help it can get. The biggest improvement you can give it is a lubricant that will allow the gears to survive the highway speeds that cars see today. L.E. gear oil is what we use in our 350 mph streamliner, that uses a V-8 quick change, without failure. The "red stuff" provides superior lubrication for long gear life. You can't win if you don't finish. We suggest 90 weight for the street and 140 weight for extreme uses.

Garage Sale - Standard Transmission Shipping Case For T-10/Jerico Transmissions
(Part #91081205)
  • Molded from ultra-high strength polyethylene and is impervious to most automotive fluids
  • Can be cleaned in "Hot Wash" systems set to 140 degree Fahrenheit or less and are designed to last many shipping cycles
  • Most containers have a tapered shape to the top and bottom which makes them widest at the assembly flange allowing for nesting of empty containers



These cases are garage sale priced because they have been used a few times to ship transmissions.
