i have a 1994 toyota camry SE 2 door v6 engine, ok so i gotta let my car warm up so it can shift right but if i dont it shifts into 1st gear late usually it shifts on 21-25mph but wen i dont let it warm up it shifts on 35mph and then after its first shift on 35mph it then goes normal and shifts at 21-25mph just wondering if it is anything i should worry about?
