J30 back from shop and now new problem..?

[cnickk]

i have had my car back from the shop about 2 weeks and i have noticed a lag between "P" and 1st gear. i let the car warm up and when i shift to reverse its ok, but when i shift into D1 its taking more time than usual. i just had my radiator replaced and new belts put on at the shop. all OEM parts were used, and this problem was not happening when i dropped the car off. any idea of why i have lag into 1st gear now???

Long shot, but have you checked the fluid level?

of course, but i understand you had to ask

i wonder if they needed to reset to ecu?? should i just go take the negative cable off tonight??
