hey guys.. newbi here.. just purchased a 1992 seville... here is my question...when at a stop .. i go and take off ...the tranny will rev up slightly and finally engage in gear... it was like this, from my friend i bought it from .. it does not do it all the time..... other than that it shifts fine .. nice and smooth... could go days or weeks and not have the problem mentioned above.. from what he can recall it started while in cruise going down the hiway about a year ago reving up slightly then engaging back in gear... after that it only does it on occasions from a stop? what could this be.. we have changed the fluid and etc...

 

Your problem is that your bands in the tranny are burnt out of it. It can be a pain in the **s to change so if you got the money bring it in to a shop or just get a new tranny.

 

Lucas sells a product for slipping transmissions. It is an additive to the fluid costs about $14 here in Canada. It does work, try that. Also just wondering if fluid is leaking out and getting low. I know you said it was changed but is it at the correct level? There are also fluid lines to the radiator to cool the fluid, these often corrode and seap out fluid and you would not necessarily know you were low. Just too inexpensive ideas you might try first before going into the unit.

hi guys.. little bit of a update... the tranny is not revving up on me.. here is what it is doing.. i checked for codes last night .. e031 "shorted map sensor" then e062 "cruise va***m solenoid".. i cleared them out... then said hell let metry something.. i put it in drive and sat there in my driveway with my foot on the brake... i actually felt it shift into neutral then back into drive..no revving up or anything... i tried other gears but it didnt do it at the time..i sat there for about 45 min doing this.. happened about 4 times that way... checked the codes.. no codes... so me and the wife go driving all day... runs smooth and shifts like silk.. no problems for about 125 miles of driving... then coming home at a stop sign it rears its ugly head.. shifts into neutral then back into drive as we are pulling off.. ofcourse it revs up a little because you have your foot on the gas when it happens sometimes... checked for codes when i get home.. no codes.. just hard for me to believe that the bands are messed up ... when it shifts so good

 

Check into this it maybe your problem

TRANSAXLE APPLICATIONS:
HYDRA-MATIC 4T60-E (RPO M13)

CONDITION:
Some owners may experience one or more of the following intermittent conditions:



^
Loss of drive (neutral condition) on highway while in fourth gear.


^
Erratic upshifts and downshifts at steady throttle angles without a Malfunction Indicator Light (MIL) (Service Engine Soon) illuminated.


^
First and second gear only (no third or fourth gear).


^
First and fourth gear only (no second and third gear).

CAUSE:
These intermittent conditions may be caused by an intermittent short to ground on the "A" or "B" shift solenoidwiring between the ECM/PCM and the transaxle or an internal electrical condition in the transaxle. In most cases, these conditions ARE NOT caused by a hydraulic or mechanical condition in the transaxle.
CORRECTION:
To diagnose this condition, it will be necessary to perform the following steps that are covered in detail under "Service Information":



1.
Check condition and level of transmission fluid.


2.
Diagnose and repair all ECM/PCM Diagnostic Trouble Codes.


3.
Identify which shift solenoid is being affected.


4.
Determine if cause is internal or external to transaxle.


5.
Identify faulty component and repair or replace as necessary.

SERVICE INFORMATION:



1.
Check condition and level of transmission fluid

Use the "4T60-E Transaxle Fluid Checking Procedure" in Section 7A-5A 4T60-E AUTOMATIC TRANSAXLE DIAGNOSIS of the appropriate Service Manual. If the fluid is contaminated, burned or contains excessive clutch material or metal, this bulletin no longer applies and mechanical/hydraulic diagnosis should be followed per the Service Manual.

2.
Diagnose and repair all ECM/PCM Diagnostic Trouble Codes

Check for ECM/PCM DTC's using the TECH 1/0n-board Diagnostics as described in Section 6E-A of the appropriate Service Manual. Diagnose and repair all DTC's prior to continuing to step three.

3.
Identify which shift solenoidis being affected

Install the Transmission Test Box J 38791 and the correct harness (J 38791-10, J 38791-20 or J 38791-60) and monitor "A" and "B" shift solenoidLED status during condition. Compare the actual LED status with the commanded gear status indicated by the TECH 1. The Shift Solenoid that is energized when it is not commanded to be energized is the affected component. (On Pontiac models, use Transaxle Electrical Jumper J 38835 and Multimeter J 39200.)

4.
Determine if cause is internal or external to transaxle

If the condition can be eliminated or changed by manually overriding the selected gear with the Transmission Test Box, then the electrical fault is external to the transaxle. If the condition cannot be eliminated using the Test Box, then the fault is internal to the transaxle. It is possible with some shift solenoid conditions that the affected solenoid will behave as if it was energized (check ball seats) without actually being energized. In this case, the TECH 1 commanded status and Transmission Test Box LED status will be the same and the condition will not be affected by the Test Box.

5.
Identify faulty component and repair or replace as necessary

Once the fault has been identified as internal or external to the transaxle and one shift solenoid is affected, the following suggestions will help to identify the exact component and required repair:
Wiring faults external to the transaxle:



^
Check for pinched wiring or worn through insulation underhood at exposed sheet metal, harness retainers or at pass-through connectors at the cowl. Underdash wiring as it routes to the ECM/PCM could also be damaged.


^
If the condition occurs during powertrain torque loads (acceleration), check for harnesses that are pulled tight against a component when the powertrain moves fore or aft.


^
Check any pass-through or in-line harness connectors for bent or damaged terminals.


^
Repair damaged wiring and repair or replace terminals and connectors per Section 8A-5 of the appropriate Service Manual.


^
On 1991-1993 Cadillac DeVille/Fleetwood/Sixty Special (FWD) models, refer to Cadillac bulletin T-93-105 or Canada bulletin 93-6E-125 (Corporate bulletin 316510).

Wiring faults internal to the transaxle:



^
Check for wiring pinched between the side cover and channel plate/valve body.


^
Check for bent or damaged connector pins.


^
Check suspect shift solenoidfor high/low resistance using nominal readings from Section 7A-5A 4T60-E AUTOMATIC TRANSAXLE DIAGNOSIS in the appropriate Service Manual.


^
The transaxle Wiring Harness or shift solenoidmust be replaced if faulty; they are not currently repairable.

Non-electrical shift solenoid faults:



^
Check for sediment in shift soleniod.


^
Check for sediment, broken/missing spring, or binding valve in shift valve train.


^
The transaxle shift solenoidmust be replaced if faulty; it is currently not repairable.

SERVICE PARTS INFORMATION:
If a component requires replacement, refer to the Service Parts Catalog for part numbers.
