transmisson

gmc s15 jimmy 214000mi auto 4x4 1995 when first start up then start to drive tranny doesnt shift, once at about 500ft it starts to warm and ok the rest of the day. should i worry about this or just let be ,starting cold wheather here in new england.this is third time in as many days

Does it take low and reverse gear good when cold?
Is the fluid level good hot in park?
Has the filter and fluid ever been serviced?
Has the transmission ever been worked on?
Any transmission codes or check engine lights?

i checked fluid other day is good,filter i dont think so as it was given to me and ithink it sat 3yrs ,i had for 2. fluid or trans repair. this suv is just my rides for around town worked fine this am , forgot to mention when starting off sounds like starting big machine at first startup untill it gets up to speed

Fluid level check when hot in parK?
Check engine and transmission for codes.
Post Back codes?
Drop pan and.
Check trans filter and fluid condition.
Also note what is in bottom of transmission pan!!!!

I think the reason most folks don't change that filter is because you have to remove that cross brace to get the pan off. It is a real PITA. Chevy, in their wisdom, put the nuts on those bolts inside the box frame. When I reassembled mine I put the nuts on the outside. Anyone that has done this knows what I mean....

checked under truck and beieve i can change filter without removing crossmember. please correct me if im wrong.as i said before this was givin to me and i had for two years dont know how long it sat at friends house but believe it sat about five years before as i notist just sat there when i moved to town. so i guess filter change shall be in order. thank you guys for all help. k

'95 must be different from the '98; there's only 1 'hard access' bolt in the '98 pan, which holds the shifter linkage...

kvn; it doesn't shift till 500 ft. You mean doesn't shift into second - right?

I think most 4L60e does that, although maybe not quite 500 ft. 1st gear in my '98 Jimmy 4L60e 180k, and my '94 vette 4L60e 87k both carry 1st gear a few feet extra when cold.

you hit it on the nose, doesnt shift to second, does this hurt tranny doing it .when it warms up it is fine thank all very much i feel relieved

Next time in the morning, let it warm up for AT LEAST 10 minutes. Put it in D, back to R, then go, and see if it does it. It still might do it anyway, but just try it...

works like you said when warm it shifts fine. thanks k
