L have a cad 1998 deville concoursit has a late shift when i take off after it shifts though all the gears its okay an it has a code 730 gear ratio not similar

Yes ,you need to replace only ,after checking vacuum line that runs to it and make sure it's working correct

Sounds like a bad shift sylenoid try flushing it but it might be to late

There is no one fix works for all on these code. Also you have left out the letter and one number of the code I assume these are P0730 and P0733, if so read on.

P0730 CHRYSLER - Incorrect Gear RatioPossible causes- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Shift solenoids harness or connectors
- Transmission mechanical problems
- Transmission hydraulic control circuit

P0733 CHRYSLER - Gear Ratio Error In Third GearPossible causes- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

PO 734 GEAR 4 INCORRECT RATIO
PO 751 SHIFT SOLENOID A PERF OR STUCK OFF
PO 761 SHIFT SOLENOID C PERF OR STUCK OFF

P0732 - Improper Ratio for Second Gear.
P0734 - Improper Ratio for Fourth Gear.

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM as follows:

Torque converter slip ratio = A x C/B A: Output shaft revolution signal from revolution sensor B: Engine speed signal from ECM C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (2nd and 4th) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

This malfunction will be caused when shift solenoid valve B is stuck open.

Gear positions supposed by TCM are as follows. In case of gear position with no malfunctions: 1 , 2, 3 and 4 positions In case of gear position with shift solenoid valve B stuck open: 4* , 3, 3 and 4 positions to each gear position above.

Symptoms: Engine Light ON (or Service Engine Soon Warning Light)

Diagnostic trouble code A/T 2ND GR FNCTN with CONSULT-II or P0732 without CONSULT-II is detected when A/T cannot be shifted to the 2nd gear position even if electrical circuit is good.

Possible Causes:
- Shift solenoid valve B
- Each clutch
- Hydraulic control circuit


Check it and tell us news.

This code means there has been excessive slip in the transmission, possibly due to lack of fluid.

Check the fluid level by warming up the car then check the dipstick with the engine still running.

Or....you may have a faulty vehicle speed sensor (VSS) located on the output shaft transmission casing.

Check the input shaft and output shaft speed sensors on the transmission. One is likely bad.

STOP Downshifting!
STOP Forcing gear change, watch the Engine RPMs and shift accordingly, HOMBRE's are as good as the operator's. Hombre's have dash shift indicators which illuminate when it's time to 'shift' and not before, This has nothing to do with gear oil either. If you've drained it, you best fill it immediately and make sure it's ample level. The heat these gears sustain in is inceredible, cooling lubricant is essential. Here's a tip, while engine is OFF, ignition key is engaged, dash is illuminated, depress clutch peddle, keep it depressed and walk through all gears with gear shift, shifting should be smooth and unpeded, including reverse. If resistance is experienced at one or more gears, gear alignment is off as a result of inproper gear shifting while driving. Continue to drive vehicle just shift slower until clutch needs replacement then do an entire drive shaft upgrade. It worth it, it's great truck.
