I got an error code pointing me to the a TCC slipping problem. I'm told that I need to replace the trans fluid pump. I was hoping to get as much input on this job as possible. I think GM has a right up on this in their service manuals. A copy or access to that would be excellent.
I finally found the part for $170 at a NAPA. Expensive bugger. I hoping to arm myself with as much beta as I can get. So please have at it. What do you all know?
Thanks in advance

whats the code 1870? if so you need a TCC regulator valve replacement,( the only replacement valve available is from a company called Sonnax.) its in the valve body and wears out the valve bore, causing lock-up slip and harsh upshifts, gas mileage stink? to fix it with the new improved valve the valve bore needs to be reamed with a special reamer only available from Sonnax thru a wholesale trans parts supplier, cost about $150 just for the reamer. take it to a trans shop and have them fix it, it'll cost you about 350.00 total. while your at it see if they'll tweak your EPC solenoid, does wonders for your shift quality.
the tq converter slipping could be anything , from the lock up solinoid to the tq converter it self
but the tq converter slips into the pump , pretty much you gotta yank the trans out and bench it , then where the tq converter slips into youll see a big round disk with i think 8-10 bolts holding it to the case
your better having the trans looked at to make sure there isnt a different issue causing the problem

^^ Especially after you have gotten to this point. My advise is buy a used one with low mileage and swap it in. Thats what i did. Just make sure you get one from the same exact vehicle or teh parts have to be changed over from the new trans to yours to fit in your engine. The bellhousings are different. good luck man.

The code was a believe 1887. If this helps at all. I was told that replacing the pump and checking the TCC valve is the way to fix this. With the prices quoted above for the valve and tool I might as well get a rebuilt trans and put it in. Of course I was hoping to avoid pulling the whole trans and replacing it.

had an 1887 code in the shop once, it ended up being a bad wire. the diagnostic procedure is a lengthy one. it may do you good to get it checked out at a reputable trans shop before you condemn the whole trans seeing as you may end up with the same problem after swapping the trans.
