Re: truck pull hard in D when at a redlight
Absolutely not normal. What makes you think it is the tranny? Do you have solid break pedal all the time? If not I would check a few things. Does it feel like you start to loose pressure if sitting with foot on the pedal? If so I would check master cylinder. You might have air in the lines. When was the last time you bleed them? Have you looked for leaks? Have you done the rear drums at all? My truck had basically no drums left at all and I would have to pump my breaks to get a decent peddle. Also check you vacuum pump and make sure the pulley isn’t seized up or wobbling or anything.
