I haven't heard the term "Hydrostartic bypass rod", but I'm guessing that is the disconnect for towing the tractor. Are you sure the disconnect rod caused the leak?
You say the tractor is slow, so I'm guessing it is really low on fluid so I wouldn't use the tractor till the transmission is back to the full level.
If you have an owner's manual it will show you where to fill the transmission, what type of fluid, any filters to change, etc., other wise perhaps a member here who has a tractor like yours can tell you how and where.

Added update

I have a club cadet series 1000 that leaks transmission fluid when the transmission bypass rod is pulled out.

After lots of investigation and stopping by two repair places; I was told the transmission was sealed at the factory and I would need a new transmission.

I got on the chat at the cub cadet site and got written instruction on how to fill the transmissions. The trick is getting to the little hole without taking the entire body apart. The fill hole is under the gas tank. Taking both tires off and disconnecting the transmission from the axle and lowering it with a jack from the body I had about 4 inches of clearance. I took the top off a ketchup dispenser and used that as a funnel. I used a little oil can and squirted about ¼ cup of 20W50 oil. The instructions said to leave about 1.7 to 2 inches from the top.

It was close. Put it back together and it works.

Following are the instructions from club cadet.

Hydrostatic transmissions are NOT designed to be a consumer serviceable part. They are filled and sealed at the factory. Consumers and those unfamiliar with servicing these hydrostatic systems should contact an authorized service center and arrange for them to perform this service.

NOTE: The instructions provided below are for those experienced in the repair and service of this type of equipment. Persons unfamiliar with this type of equipment should employ an authorized service center to perform this service. Please utilize the service center directory on this support site to locate a local authorized service center. For specific model hydrostatic transmission service or repair information, please contact Hydro-gear®.This company manufactures most of the hydrostatic transmissions used on our products.http://www.hydro-gear.com/Home.aspxOIL TYPE:

Normally replacing fluid is not necessary unless the drive system is damaged, leaking or in need of other internal service. Hydro-Gear® factory uses 10W-40 motor oil during assembly, but also approves the use of 20W50 oil when servicing the hydrostatic system and this oil needs to be replaced. The actual recommended transmission fill level capacities vary by transmission model, although most hydrostatic transmissions are filled to between 80-90% of capacity, leaving an air space for oil purging gas collection and venting. DO NOT COMPLETELY FILL OR TOP OFF the system with oil as a small air space within the transmission is necessary for temperature related fluid expansion, trapped air bubble collection, system self-purging, and accumulated gas pressure venting to the atmosphere is necessary for these fluid drive systems to operate smoothly. OIL

LEVEL INSPECTION: On many Hydro-Gear® hydrostatic transmissions, there is a inspection cap near the top of the transmission case that may be removed with a 1/4" allen wrench. The oil level may be checked at this inspection port using a clean popsicle stick, or similar available clean dip stick tool that will register the inside fluid level with relation to the access port and provide a estimable distance, nomal level is 1.7"-2.0" from the access port, which will then allow for the proper air expansion space.* Since these transmission vary in size and shape and the location and availability of ready access to inspection points may be impeded by product application, the service person will sometimes have to estimate, to the best of their ability, whether or not capacity is within the above mentioned 80-90% capacity range after the transmission is assembled onto the unit.

*CAUTION: DO NOT drop anything inside the transmission as it can cause damage to the unit.

That's great news.

For those tight places I found this hand fluid pump to be a handy tool to add fluids to axles.

After some research I found that the Performance Tool Quart and Gallon pump fits the most one quart bottles perfectly. The hose that comes with the pump is very short so I went to Lowes and got 6 feet of 3/8 inch plastic tubing. The pump is very inexpensive, just plastic. To remove the short plastic tube I heated it up under hot water and used a butter knife to help push it off.

To order the pump you can use the link below:
