The filter is the  Problem But Unfortunately
not the cause,

See  ,           the filter get`s blocked with Debris ,
then in turn, creates Low oil Volume to all and everything in your transmission Creating Havic to You...  The Driver ,
But the problem stems from the Clutch Material  Flaking off the Clutches ..  
So like i said  The Filter can be replaced ... By Removing the Tran`s ,   But  , What the *** your  half way their ,  Fix the Problem  and you,ll be done . Yep  It`s Rebuild time ...........

cleared codes, now i get only the knock sensor code.just put tranny in{came out of 94 truck with 46.ooo mi.)when i raise it up and run it, i can hear and feel it trying to catch 3rd.worked fine in other truck...fluid looks good(light coat of dust on magnet)no burnt smell.  

Did you drive it with the code`s cleared ?   and did it work ok  or not ???????????????  
Hog Rider

yes,cleared codes. drove it and still only 1 and 2. only 1 code-43  

rotcoddam22  It sounds like your 3rd clutck pack is shot , But in one of your postings you wrote (3rd when prompted by manualy sending signal from ecm} did you ground the solonoid to acheive 3rd. gear ? I,m unsure ?
Did the unit work in the 94 truck ?  
Hog Rider

yes, grounded it at pcm. and yes, worked fine in the other truck.only diff. is , i had a b&m shift-plus wired into the pcm.  

Please help if you can. I may have to rebuild my A500/44RE transmission and I cant find a step by step illustration to do so. I dont even know if I really have to rebuild it but I know I cant afford a shop. My problem is posted...  

Hi Hog Rider,

I have a 96 Blazer that won't shift out of first until I let off the gas. It then shifts into third. Second and fourth are gone. When it downshifts from third, it goes into first.

The fluid smells fine. I drove it that way for a couple of days, when it finally threw a code of P1870. Any clue as to the problem? Is this major, or maybe a solenoid?

Thanks  

rotcoddam22 ...
Someone wired your truck wrong !   Think about it ... It work`s when you manully ground it but it dont when you drive ! But it Still should throw a code if the wires are wrong, Research the newlly installed shifter wires

BlazinBoy  Bad news    The Band inside the unit has failed   . This band  controlles 2nd. and  4th. gears !
1870 is a Internal slip code , You can swap the   A and B  solonoids if you would like to try  but I,m sure you,ll find you have waisted your time.  
Hog Rider

Thanks for the fast reply, even though it's not what I wanted to hear. Any thought on having it rebuilt vs. a reman? How expensive is fixing it vs a reman?  

BlazinBoy   Depends on what part of the country your in ,  Here on the  East coast  a Rebuild could range  $700 to $1800
where a reman  will have a set price  around $1200
salave yard  about $300

hollaatcha ,
Get it scanned for codes , Send them to me  ( You must have some kind of code)   are you sure it`s the Trans and not Motor problem ? Ie. Catalitic converter ?
