transmission rebuild

Alright, so I made call to see what a simple engine rebuild would cost me. The figure I get is 875.00 which sounded fairly reasonable. Chime in if I am off base here. Then I call to see what a transmission rebuild would be. They tell me 895.00 which sounds pretty off considering the cost of the engine rebuild. I am not sure what transmission I have but that seems a little high to me. Am I missing something???
