I recently replaced the 700r4 trans in my car with a raptor 700r4.After a test drive everything seemed to work fine.the next time I went for a drive if felt like by brakes were applied.the trans was not slipping but the car seemed like it didn't want to move (feels like when you leave your parking brake applied).this happens in reverse as well as drive.when i pit it in nutral it goes away.Please help
