Hi all,
Things have been busy around here with moving and all. Getting the new shop setup now with heat, lights and shelves, the job moves forward.

With the help of some good friends I have amassed a collection of core transmissions in the last two weeks and have a list of hybrid transmissions I will be offering at this time. I have parts to build these all and they are offered on a first come basis. The OBX will be ordered as requested by the customer.

At this time I'm offering a free drain plug and the shipping container and packaging material with each transmission purchased

None of the transmissions are assembled so you can select the options you want like moly plate, OBX and drain plug. The OBX in NOT available on the 525/555 transmission.

Moly Plate for the 525/555, 520/555 is an additional $100.00

OBX Differential with new internal washers, disassembled and all holes tapped and case clearanced for proper axle fit $550.00

NOTE: This is for the 520/555 and 523/568 transmissions ONLY. Will NOT fit the 525/555 transmission.

The reason for the added cost on the OBX is that all but one we have had here came with broken belville washers inside, fasteners not torqued right, bolt holes not tapped right and axle shafts that wouldn't fit into the unit, we fix all these issues.

525/555 transmission. This is the combination that started my hybrid adventure. I built my first one 12 years ago for a friend with an '86 GLHS that wanted the strength and better ratios of the 555 along with the 3.56 FD ratio of the stock 525 and a transmission that wouldn't require cutting of his very nice GLHS, a bolt in custom transmission shall we say. We added his Shelby Cam & Pawl posi unit and a Lambros moly plate and this transmission still runs today in his car.

525/555 transmission. 555 1st thru 5th gears & input shaft. 3.56 FD intermediate shaft and ring gear from the 525 and stock 525 differential. Rebuilt with new bearings, seals, shift fork pads and brass as needed. Upgraded 1/2 shift fork to the HD piece from the 555 along with an '87 525 case that uses the stronger differential bearing retainer bolts on the left side. $725.00

520/555 Transmission. 555 1st thru 5th gears & input shaft. 3.50 FD intermediate shaft and ring gear from a 520 with stock differential and diff pin retainers. Rebuilt with new bearings, seals, shift fork pads and brass as needed. $800.00

520/555 Race/Street transmission. 555 1st thru 5th gears & input shaft. 3.50 FD intermediate shaft and ring gear from a 520 with a stock differential and diff pin retainers.

This race proven street crash box has had modifications to the gears and brass rings. Every other tooth was removed from the 1st thru 4th speed gears and the brass rings to allow full throttle, to the floor power shifting. This transmission setup was race proven with over 100 passes in a 12 sec. Shadow and the final cause of failure in that transmission was the stock differential when the motor and transmission were installed in a full curb weight Spirit R/T, blew the pinion gears all over the Englishtown starting line, NICE.

If your looking for something that shifts like no other here, is your transmission. You can have it with a welded diff for no extra charge for your race only application or add the OBX for a street strip car. $1000.00

R/T 523/568 This is a new combination I came up with to offer the R/T owners the choice of having a Quaife unit without the Quaife price. 1991 R/T transmission with a 3.77 FD intermediate shaft and ring gear from a 523. A good choice to keep close to the stock 3:85 FD ratio and allows you to install an OBX LSD unit. Rebuilt with new bearings, seals, shift fork pads and brass as needed. $900.00

Shipping is by way of Fedex and calculated by your ZIP code to a work address.
