**97' lumina- Question Please Help!!!!!!!!!

My car won't go into gear after starting it after it has sat over night. It either takes time to warm up, or I have to put it into gear and rev it up itill it "slams" into gear. It obvious I'm not car genious, so I'm looking for possible suggestions. Also, once its in gear and I pull up to a stop sign, and then accelerate again, the car will shack and vibrate intenslty intill it goes into gear. :banghead:

Any help would be appreciated.

Sounds like low or burnt up fluid. Pull the stick, engine on, and "hot", wipe the stick clean, then put it back in, hold the brake pedal an go slowly throught the gear selections and back tro park, then check your level on the stick.

Also note what color the fluid is. Pinkish-red good, brown and smelly lik eold coffee, bad.

Thanks for getting back to me. However, I took it in about 6 months ago to have the fluid flushed when I started having the problem with it.

Any other suggestions for me??? Do you think this is a tranny issues or something with electical?:banghead:

That clutchpack shudder usually means you're looking at a tranny disassembly...

How's it hold once you get moving? Stay hooked up and shift OK, or slip between shifts and fall outta gear when you take your foot off the gas?

It stays in gear once its in, but when accelerateing from a stoped position, it shakes intensily and somtimes you can hear the engine accelerating, and I won't be moving much, then it will "pop" into gear.

But once I'm moving past about 20 miles and hour, accelerating is fine.

Some general info:

Delayed Forward



Improper fluid level.
Improper band/clutch application pressure.
Filter damaged or plugged.
Main control assembly gaskets damaged or bolt out of torque.
Main control separator plate damaged.
Main control solenoid stuck or damaged.
Pump assembly bolts out of specification.
Pump gears damaged or cracked.
Overdrive one-way clutch damaged.

Low line pressure? It could be a modulation issue, and not just the pump. Screwing a gauge ot the test port would be an easy way to find out.

I'd do that too....but it sounds like some I've run across with a cracked input drum that bleeds off fluid pressure until it warms up, then the crack tightens up and holds better.

That's my official, semi-educated, remotely diagnosed, shot in the dark worthless opinion.:grinyes:

Either way it is coming out!!
