It shifts into 1 and 2 but won't go in 3 just free balls and it just started change filter fluid and still won't shift

Can you pls help

Neutral or electrical box

fairly mechanically inclined. live in Alaska, yes its cold! so i drove to work, and when i got off work my truck would crank but not start, my buddy told me it was not getting fuel and i needed to change the pump. i changed the fuel pump relay and she fired right up! the next day it did the same thing crank but no start, this time i unplugged the fuel pump relay for half hour or so plugged it in and she started! went home and changed the fuel pump anyway. the next day the same thing, crank but no start! now its -30º F here so i had it towed for $100 bucks to my house, rolled it into garage and for shits and giggles i turned the key and she fired right up! my kind of luck. whats going on? recent history before this started, just replaced the water pump, thermostat, thermostat sensors. no codes being thrown...

Relatively new motor, new heater core, new water pump, new thermostat(x3). New blend doors (operational i checked) head gaskets replaced and heads milled, hoses seem to get hot, upper hose on core from to p of engine seems to be hotter than the lower return to radiator. temp gauge never goes above 70-80 ish was not working so i installed an aftermarket gauge and the increments are not that well designated... ive done everything i can think of. and spent way too much money. never had this issue until last winter, this truck used to have really good heat, last year and this year wearing snow pants to and from work cause its - 30- -40° below here in AK Sux.

Engine immediately trips check engine light
Both sensors were replaced
New vacuum hose on map sensor as well
When it first starts it barely runs then a few seconds later settles into so so idle semi rough idle

The noise is coming from the right side of the engine, and only happens when I accelerate.

A month ago I changed the fluid and filter in my truck, and now it slips while driving it.

My pickup drives like my brakes are locked. And a mechanic told me that my pedals are very low. This has been a problem for the past two years.

problem happened after pulling engine to replace freeze plugs

I have a 94 Chevy Silverado Z71 and while driving my truck will stop running for about a second then come back to life but sometimes it wont. it also tends to stall a lot when trying to leave a stop sign or a light. We have changed the fuel pump, fuel filter, cleaned all electrical grounds, throttle positioning sensor, spark plugs and wires are fine, and changed O2 sensor. Anyone know what it could be?

starter replaced now pickup will not start turn the key to start but nothing will happen dash lights up everything else works but dead when try to start

It's a fluid trans and it doesn't want to shift

check engine light comes on and off

When cranked its backfiring .When you first started up while its idling and while operating the vehicle and when it's turned off.
