Default tranny help!!!!

guys i need help.

so its been a few months now and my trans is still broke.
i have taken it to three different places and they are all stumped.
the last thing to do is to rebuild it.
i have had the trans rewired, solenoids tested and they passed, filter and fluid changed, and also had computers hooked up and everything is working properly but the truck will only do 73 mph to the floor at 2750 rpm

any idea?
please help me its costing me so much money and im only 16 and cant afford it much more

are you sure it has nothing to do with the fuel pump? like it is getting fuel but not enough of it. i mean if it checks out at three tranny shops and it shifts and makes it way to o/d,. then i would start looking else where. that is just my 2 cents before paying for a rebuild.

p.s. have the bands been adjusted on those tranny shop visits?

my truck was running fine before i did my 3kgsk but the stock springs were at .026 so they did not have much tension on them. that could be his problem.

If you did put in a GSK MAKE SURE TO TAKE OUT ALL THE SHIMS. Also, have any of them checked the torque converter?

thanks for getting back to me guys

i have had the bands adjusted during those visits and they all said there wasnt a need to check the convertor because it was locking up and didnt seem to be slipping.

i think the truck is getting enough fuel it smokes like a train at low boost and once my hx35 clears it up there is still a good haze.

it has stock gov springs i really want to buy them but my dad thinks im gonna blow up my truck the way i drive it

i hope this helps, i need to figure out this problem.

could having 218k miles have anything to do with it? like a slip in timing or like yall were sayin bout the stock springs not having tension, do they come loose?

also i forgot i have the 3.54s in it too i love em

even with my up trans or whatever i still walk my dads 24 valve

(the one in the sig.)

swapped out the gsk. a 3k wont blow anything up.

this is gonna sound stupid but, make sure the gas pedal is moving full travel. when i bought my truck it would only do 2900rpm come to find out the throttle cable strected and i wasnt getting full fuel... i put a bigger spring in there till the new cable cam and she runs perfect now.
