3rd gear is slipping.....

ok, last oct had a radiator/ inner cooler wall go bad and get radiator fluid into my transmission.

now starting to feel a constant surge while going up hill ( accelerating at constant rate) while only when im in 3rd gear,

is there anything i can do cheaply to keep this from going entirely south for a few more months.

gotta get my student loan check for fall semester.....=|
