tcc solenoid?

[trx88]

im having trouble with this trans also dumping into o/d at lower speeds, like it wont hold third or 4th. i always thought it was because the tires so big with 4.88's is confusing the ecu and the sensor at the trans output shaft, but i might throw a 3-2 solenoid in there while im at it!

honestly id replace all the electronics while your at it, if you go to my thread in the transmission section on one of the pages i posted alot of good part deals, the name of the thread is answer to all your 4l60e problem or something like that, its sticky, but you can get the entire electronic setups in the pan for around $130

well i replaced the tcc solenoid put the pan back on and put 5 qts in

if i put it into gear, it dies, if i put it into reverse, it kinda idles down but it stays running.

hmmmm, thats interesting, howd the fluid look? and do you have any engine codes?

 

[trx88]

fluid was browner than red, not complete trash though.

no codes, truck has a brand new 5.7 crate. BRAND NEW. 50 miles on it.

i was more asking about the engine codes because tranny codes will come up too, read the trhread i started a while back and let me know if any of the symptoms sounds like anything in the thread

I think the torque converters trashed

 

[silverado13]

is it making any sounds? or shuddering?

 

[trx88]

well right now its not doing anything because unless im in neutral or park it will die, it suffers to run but stays running in R

before this it had some other issues that I attribute to having 4.88 gears and 35 tires, not calibrated.

im looking for a new trans/converter combo. but im not buying anything less than a good built one

 

[silverado13]

id try one thing at a time and go from there because you dont wannt have to replace your whole tranny and it of only been the torque converter, i personally think that the best converters for the price are the ones at monster transmission, i have a 2000 stall rated up to 550 foot pounds of torque and i think i only paid somewhere around $225 for it, but you should check out their transmissions too
