I recently changed a & B solenoid and tranny was fine. then when driving it would not take off from od or d selection but if i placed in 1st or 2nd it would go then tried to place in d while driving it would work somewhat but would slip.did have tranny shaking in od or d when trying to go from a stop or a coasting speed.but not always. fluid changed and new filter. no codes.how many quarts of fluid is recommended? thanks.tranny rebuilt once in 2000. 1996 chevy s-10 4.3. wiring harness also changed in 2003.

 

The sprag may be going out. I lost the sprag in a 60 once and had no forward in OD (4) or D (3). I could take off in first or second because the overrun clutches were holding.

 

well i know longer have any od or d had to get it home in 2nd, she ran pretty hot temp. it was bubbling, think im sol

 

Definitly sounds like a sprag issue.

 

thats not all that bad to repair then is it? how much harm did i to tranny driving it home like that? how much is this to repair and how difficult . I do have alldatadiy.com
If i can find all info .thanks guys hope this is it.

A/T - Upshift Flare/No 3rd or 4th/Launch Shudder

File In Section: 07 - Transmission/Transaxle

Bulletin No.: 00-07-30-026

Date: December 2000

TECHNICAL

Subject:
Automatic Transmission 1-2 and/or 2-3 Upshift Slip/Flare, No 3rd or 4th gear, Launch Shudder (Revise VCM Wiring)

Models:

1996 Chevrolet and GMC C/K, S/T, M/L, G1, G2, P3 Models
1996 Oldsmobile Bravada
with VCM and 4L60-E (M30) or 4L80-E (MT1) Automatic Transmission

This bulletin is being reissued to ensure that correct procedures are followed for this condition. Please discard Corporate Bulletin Number 66-71-03A (Section 7 - Automatic Transmission).

When performing a transmission replacement labor operation K7000 on these vehicles with a 4L60-E or 4L80-E, you must include front chassis wire repair labor operation N6112. Inspect the VCM to verify the latest part number revision (16244210).

Condition

Some owners may comment that the automatic transmission has either a slip or flare on the 1-2 and/or 2-3 upshift, or no 3rd or 4th gear, or launch shudder. Upon investigation, the technician may find a DTC P1870 stored in the VCM.

Cause

A poor internal ground between the two circuit boards of the VCM may cause the VCM to command erratic line pressure at the pressure control (PC) solenoid valve.

Correction

Using harness jumper wire and instruction kit, P/N 12167310, revise the wiring harness at the VCM connector. Corrections were made to the VCM beginning 2/14/96. The corrected VCMs are identified with service number 16244210 on the VCM identification label.

Procedure

The following is a summary of the instructions included with the service kit:

1. Remove the negative terminal from the battery.

2. Move the wire located at connector J3 (WHITE/GREY/CLEAR), pin 18 to connector J1 (BLUE), pin 23.

3. Install the jumper wire between connector J2 (RED), pin 26 and connector J3 (WHITE/GREY/CLEAR), pin 18.

4. Install the tag included in the kit around the. VCM wiring harness. This tag notes that the wiring harness has been modified.

5. Reconnect the negative battery terminal.


Road test to verify that the condition has been corrected. If any of the following conditions are noted, the transmission should be repaired or replaced using the most cost effective method. Canadian dealers should repair the transmission.

^ Transmission fluid oxidation or excessive sediment.

^ Transmission slip or flare after this service fix is performed.

^ DTC P1870 is stored on a 4L60-E (M30).


The following tools are available from Kent-Moore (1-800-345-2233) for use in removing and relocating the VCM wires:

^ J 41758 Terminal Tool; used to remove the wire from the VCM connector.

^ J 41759 Punch; used to punch a new hole through the connector seal.

Gear Train, 4L60E, which one is the spag part:

 

have all info on 4l60 e if any one needs it. im mean everything except how to tell whats wrong so many things cause same problems it seems.

 

Not a very clear diagram, but part #42 appears to be in the right place and the right size.

This is a 4L80-E HD sprag, yours will look similar:

 

thanks james

 

now today mil went on and i got codes 753,758,1860,1864 and 1886. but tranny now has drive again no od cleared codes and thenj there was no drive again so i pulled the fuse and mil went back on and got same codes. so my ? would it be the sprag still.
or somthing else maybe. ie wiring harness

 

well I went with the 97 just got done with install but low and behold now I have nothing at all, old trany at least had 1,2,r
after topping off fluid ran truck for 20 mins still on front wheel ramps went to drive it down and test her out and nothing all gears, here is what im seeing wrong dissconnected top tranny cooling line from the rad and no fluid flowing, fluid is showing full in this position and dip stick would be up so if anything should read low then I called it the nite. so is it because im still on ramps or is pump shot or did I forget somthing I did check to see if I did dont see anything off hand, except hose on top center of trany is this vacume or overflow? this is a used tranny.

 

That's a bummer, I understand your frusteration.

Does it have a filter in it?

 

tranny is out of 97 jimmy, I took out tranny and it looks like i didnt get it seated all the way because off the way i did it.
pump and torq conv. was not seated looks like i busted up the pump. now can i take the pump out of old tranny and put it in the 97 and how . can i take pump out without getting hit with a tons of springs. now i know why it cost so much to rebuild and replace tranny. really isnt that easy to do in home garage. would have been if i known that you should place torq on tranny a fit it that way but thought it was very well lined up but wasn't and busted pump up.
would take it to a shop but everyone is behind 2 weeks so how do i get pump out do i need to tighten bands before doing anything or can i just go and take pump.
omne thing i cant see is how you would tighten torq to flywheel is there enough room sure doesn't look like it .
