T5 Overdrive Transmission Adapter 


5-Speed Your Flathead 6!

The use of an adapter plate to mate the 4/6-cyl S-10 5-speed (T5) transmission to the Mopar flathead engine requires that you use the transmission with the longest input shaft and a clutch disc with a reversed offset hub to assure proper spline to clutch hub engagement. The input shaft also requires a special crankshaft pilot bushing.

Our kit includes a machined aluminum adapter plate w/flat head machine screws, a clutch disc with a reversed offset hub, a longer clutch pivot bolt and an Oilite crankshaft pilot bushing.

The popular transmission is the S-10 because its design offers the forward mounted shift lever. Its location is about 11? back from the flathead clutch housing or the early floor shift location. And, the S-10 tail housing can be installed on all T5 boxes.

The adapter plate is 5/8? aluminum, blanchard ground and CNC?d to accurately mate the T5 to the stock clutch housing.

The clutch disc is a GM 9-1/4? disc with an offset spline. The hub has been reversed to get more of the S-10 input shaft into the disc. The pilot is a high-quality Oilite bronze bearing.

You are to supply your own clutch throw-out bearing and sleeve (collar). The stock Mopar clutch throw-out bearing and sleeve can be used by honing out the sleeve to match the S-10 bearing retainer. Or, the retainer could be turned down to mate to the sleeve. An alternative would be to press a sleeve over the stock S-10 bearing retainer and machine to accept a 1994-2001 Cherokee throw-out bearing assembly. This will mate to the later stock clutch fork. Another alternative is to use a Ford bearing retainer, which will accept the 1994-2001 Cherokee throw-out bearing assembly. The mounting flange on the Ford retainer needs to be turned down slightly to match the S-10 for piloting into the adapter plate.

Before starting this project it is recommended that you become familiar with the B-W T5 transmission. There are many sites that cover the history of this design and give good information on its flexibility, available gear ratios and applications. You should also confer with a T5 specialist such as Tom Langdon in Utica, MI (586-739-9601) when you are ready to buy.

Follow this link for pictures of how I did it in a P-15. I have driven about 15,000 miles with this setup up and no problems to date. With the 30% overdrive reduction and a 3.55/1 differential I can run 70 MPH with my engine turning around 2200 RPM's. I also upgraded the differential from a 74 Charger and this fixed my emergency brake issue. I do have a long block Desoto flathead engine in my car.

Go online and look up genie shifters and also I think Hagen has e-brake setups that look almost like the original hand brake lever. Grab a hotrod book and you will find adds in most of them.  Wayne from California

My memory is really poor, but I know that I read somewhere - either on the POC or the WPC - that a Chev S10 5 sp can be installed behin any generic DPCD 6 cyl non fluid drive flathead. If this is so, does anyone have suggestions re the installation of a hand brake to replace the original? I'll really appreciate any comments/suggestions.
