With foot on brake i shift into reverse and it slams hard. Once i put in drive and drive forward it also shifts down hard when coming to a stop. If i shift into 2nd and drive forward it doesnt do the hard down shift.

This could be due to a variety of reasons such as a faulty shift solenoid, internal mechanical failure with the transmission, or an issue with the transmission fluid.

It's possible that the car's transmission was damaged when it was stuck in the snow drift. The slight pause shifting from reverse to drive that you mentioned earlier could also be an indication of a transmission problem. I would recommend taking your car to a qualified mechanic to diagnose and fix the issue. You might get lucky-- but without a visual inspection, you may just hear the intimidating prognosis of a transmission problem.

In the meantime, you can try holding your left foot on the brake while you shift into reverse. Then, as soon as you feel the transmission engage, gently depress the gas pedal with your right foot. This will eliminate the forward roll problem .

The question is a little vague but I think I know what your referring to. All modern automatic transmissions have torque converters. This is the device that connects the engine to the transmission. All vehicle manufacturers like the trans to be nice and smooth shifting. That's great but it does come with some minor drawbacks. If you are facing slightly down hill and you put your car in reverse but do not step on the gas slightly I can guarantee that you will indeed roll forward. You can eliminate that issue by holding your left foot on the brake while you shift into reverse. Then, as soon as you feel the trans engage, gently depress the gas pedal with your right foot and it will eliminate that forward roll problem.

Sounds like an automatic transmission problem, specific the clutch. Either a rebuild or a new one. Check the fluid level and smell it to see if there is a strong odor. The collar should be cherry red. If it's brown, it's cooked.

You can shift between 2Hi and 4Hi when the truck is moving. Just let off the gas and shift it. But in order to shift to Neutral or 4Lo you need to stop the truck and shift the transmission into neutral then shift the transfer case.

Quite often that will happen when vehicle parked with wheels turned, and/or vehicle on a slope, so try to avoid that in future.If nothing else, when parked on a slope, stop, keep foot on brake pedal, apply parking brake, put transmission in neutral, then take foot off brake pedal and wait for parking brake to stop vehicle rolling, then shift it into park. When leaving, put foot on brake pedal, shift to drive or reverse whatever direction your going, then release parking brake. Sounds like a lot to remember but you won't have to pull hard on shifter as before, and it could save a lot of money on transmission repairs down the road. Always try to park with wheels straight as well.
Now, with that said, if you parked with wheels turned, try hard to turn steering wheel in same direction wheels are turning, just slightly, as you try to turn key. Sometimes a quick yank in that direction will do it. Also make sure shifter is all the way in park before you try it. If your on a slope try rocking vehicle slightly up slope as you push/pull shift lever in to park and try to turn key at same time. If no luck, try pushing brake pedal real hard and try to turn key. Let me know how it goes.

Is it only when you go from park to reverse? Or is it just as bad going from neutral to reverse? I've noticed on mine that it's often tight if I park on even a slight slope. If it only happens when going from park to reverse, try this. Hold your foot on the brake, and put the car in drive. Keeping constant pressure on the brake, go back to park, then back into drive. Did you feel the stiffness when you had your foot on the brake?

The damage potential is with accidental shifts out of PARK, such as with kids playing around or the accidental shift by an otherwise occupied driver. To prevent accidental shifting out of PARK, car makers years ago started installing the safety interlock which requires a foot on the brake pedal before shifting out of PARK and putting the car in motion. No damage potential in shifting between other gears, as long as the vehicle is stopped. I hope that this answers your question and wins the debate for you.

could be a vacuum leak between engine and booster

1st, is your foot on the brake? That's a safety feature, u must depress the brake pedal before u can shift out of park.

Put the transmission in neutral, emergency brake off, foot off the brake pedal, now try shifting out of 4 wheel drive low. If that doesn't work, drive forward, and again do the above, trans. in neutral, roll to a stop, foot off brake, try to disengage. What you're probably experiencing is called drive shaft 'wind up', and it is very difficult to disengage, but do the above and it should shift out of 4 low. countrycurt0
