Would like to know of any transmission issues

It sounds like there might be an issue with the installation of the new wheel bearing, or a related component. Grinding and whining noises are often signs of mechanical issues in the drivetrain, and if the problem only started after the wheel bearing replacement, it's likely related to that.
I would recommend having the vehicle inspected by a qualified mechanic as soon as possible. They should be able to diagnose the issue and determine whether the problem is with the new wheel bearing, or another component in the drivetrain.
In the meantime, I would avoid driving the vehicle as much as possible, especially if the grinding and whining noises persist. Continued driving could cause further damage and make the repair more expensive.

The issue you are describing with your 2000 Dodge Grand Caravan, where the dash says "reverse" when the vehicle is actually in "park" and the key can be removed while the engine is running, is likely related to a problem with the vehicle's transmission range sensor or park/neutral safety switch.
The transmission range sensor is responsible for sending a signal to the vehicle's computer indicating the position of the transmission shift lever. If the sensor is malfunctioning, it may send an incorrect signal to the computer, causing the dash to display the wrong gear position.
The park/neutral safety switch is responsible for preventing the engine from starting or the key from being removed when the transmission is not in the "park" position. If the switch is malfunctioning, the engine may start and the key may be removable even when the transmission is not in "park".
It's best to diagnose the problem by a professional, or if the vehicle is still under warranty, contact the manufacturer for assistance. It's important to note that these are general steps and the specific procedures may vary depending on the exact model and type of your vehicle. It's recommended to consult the user manual or contact the manufacturer for the specific instructions and precautions for your vehicle.

To override the parking brake on a 1993 F700, you will need to disengage the brake manually. Here are the steps to follow:

1. Locate the parking brake lever inside the cab of the vehicle. It is typically located near the driver's seat, on the floor or the dashboard.
2. Pull the parking brake lever up to the fully engaged position. This will disengage the brake and allow you to move the vehicle.
3. Start the engine and shift the vehicle into gear.
4. Slowly release the parking brake lever, allowing the brake to engage gradually. Do not release the lever too quickly, as this can cause the vehicle to lurch or jerk.
5. Slowly drive the vehicle, testing the brakes to make sure they are working properly. If you experience any problems or issues with the brakes, you may need to have them checked or repaired by a qualified mechanic.

Overall, to override the parking brake on a 1993 F700, you will need to disengage the brake manually by pulling up on the parking brake lever and releasing it gradually. Make sure to test the brakes before driving the vehicle to ensure they are functioning properly.

Based on the symptoms you have described, it sounds like there may be an issue with the transmission in your Mazda 3. The loud clicking sound when shifting into reverse could be a sign of worn or damaged gears, while the hesitation and lurching in first gear could be due to a slipping or malfunctioning clutch.
It's also possible that there could be an issue with the transmission fluid, such as low or dirty fluid, which can cause shifting problems and other issues. I would recommend having a qualified mechanic inspect your vehicle to diagnose the exact cause of the problem and recommend the appropriate repairs.

I bet you its low on transmission fluid. Check fluid level while engine running.

Hello Kim,

Lurching and "impedeing" is not the most comprehensive
description I've ever heard.

That could describe everything including
wheels falling off... flat tires...
LOCKED UP CV-Joint... dried out oil-less manual transmissions .. to pistons sticking outside the engine block.

Perhaps you failed to pay a pile of parking tickets...
and have a wheel-lock attached? ((I'm just saying))

My best "ADVISE" would be to guide YOUR "lurching and impedeing" down to your first local muffler shop that offers FREE READING...

(FREE is a relative term) ... Have them READ your
DIAGNOSTIC TROUBLE CODES... For a good starting place.

It would be WISE to know the prices of some of your "PARTS"
before you go...

Or you could relate more relevant details... year, engine displacement, tranny type... Maintenance history and
POST a better question... provoking a better answer.

Hope I'm helping!

Heavy load in park sounds like a transmission issue. The torque converter and transmission pump are still spinning in park

These transmissions are not difficult to fix as long as you are meticulous in cleaning and replacing EVERY o-ring and seal.A general mechanic would most likely not understand the importance of this or have the knowledge of honda automatics to repair it successfuly. If he charged you to fix it and it is not then is his problem till he refunds your money or makes it right.I always replace the torque converter and instal a new cooler so i know there is no remaining trash from the original failure in the system. Flushing the original cooler is dam near impossible.The filter is internal and just a little trash will restrict it and cause all kinds of bad symptoms especially when it is cold and the fluid is thicker.Without knowing the 4 digit code on the trans it is hard to get more specific on the source of your problem.

I would very first recommend checking your transmission fluid. It may be low and would cause the lurches and the rough shifts.

Lurching? You mean kind of jerking when accelerating? Another person had a similar problem. To not be repetitive, this great diagnostic article points out to six possible causes of this problem:
