Tranny Problems HELP!!!

:banghead: I have a 1996 Bonny. It started something very strange to me. When the car is first started it will go great for about 1/4 mile, then the trans will slip so bad that it will not move the car. If I turn off the car and restart it after about 30 seconds it will move for about another 1/4 mile. When the car is moving I here a strange rattling seemingly coming from the bellhousing. If anyone knows what might be causing this problem please reply.

It's coming out!

If its coming from the bell the torque converter could of failed and plugged the filter. as for driving for a 1/4mile then slipping & shutting the engine off and then it works fine again. That’s a sign of a plugged filter.

I have decided to replace the tranny. will it be a hard job? I have considered a getrag 5-speed or a 4t65-e. will either be extremely hard?
