Automatic trans am i right , hope so but your transmission has gear solenoids and it sounds like your 3rd gear solenoid has gone out . the trans oil pan will have to come off in order to replace this solenoid .

Fluid and filter would affect all gears not just one . I would run the fault codes and look for a TCM problem with a solenoid /servo problem for 3rd gear.

SOURCE: 1995 sunfire wont shift gear

There were two different automatic transmissions in the Sunfire that year,the 3 speed trans designated the 3T40,and the 4 speed trans designated the 4T40.If your car has the 4 speed trans,there will be a circle around the "D" on your gear selector indicator.The 3 speed trans will not have a circle around the "D".The 3 speed trans works off of a cable called the TV or Throttle Valve cable.This cable should be checked where it engages the throttle body around the area where the throttle cable attaches to the throttle body,on the engine.If the cable becomes disconnected for whatever reason,the trans will not shift out of 1st gear in most cases.If the car has the 4 speed trans,this model trans is totally electronic,and the vehicle should have the codes pulled out.For every trouble code,there is a diagnostic route to follow to repair the malfunction.

Codes p0700,p0733,p0734 dodge caravan 1997


P0700 is a informative transmission code, about some problem there; the P0733 and P0734 is the specific problem there.
I would first try changing the fluid and filter. Although the fluid may look like it is brand new, with 100K on the fluid, I can assure you that even if those miles were all highway at steady speed and no load that the fluid has deteriorated and no longer lubricating the internal parts properly and that there is some debris in the ******.If codes return and shifting problems are still present, there is definite internal failure, possibly the pump or in the clutches.
DTC P0733The powertrain control module (PCM) uses the crankshaft position (CKP) sensor, input speed sensor (ISS) and output speed sensor (OSS) to determine engine speed, input shaft speed and output shaft speed. These sensor readings are used to determine the current gear ratio and RPM slip across the torque converter. The PCM uses this information from the sensors to determine if the commanded gear matches the actual gear. During normal driving conditions, the PCM will adapt main line pressure via the pressure control (PC) solenoid to prevent slipping and harsh shifts. Shift solenoid 3 is used to apply or release third gear clutch. The PCM controls 3rd gear by controlling the ground for shift solenoid 3. The PCM will turn the solenoid OFF, open the driver circuit, when 3rd gear is commanded On to apply 3rd clutch. Shift solenoid 3 is supplied ignition voltage from the fuel pump relay whenever the PCM commands the fuel pump relay ON. DTC P0733 sets when 3rd clutch still slips after the PCM has commanded high main line pressure.DTC Parameters
DTC P0733 will set if the PCM detects an incorrect actual 3rd gear ratio when 3rd gear is commanded On when:- The condition exists for longer than 3 seconds (2001)*- The condition exists for longer than 3 seconds, 1 minute is allowed to elapse, then condition exists again for longer than 3 seconds (2000)- The high main line pressure has been commanded- The transaxle is in a forward gear- The input speed is greater than 224 RPM- The vehicle speed is greater than 5 km/h (3 mph)- The speed noise parameter = NO- The steady state ratio fail counter equals 255 for an in-gear failure, or the shift fail counter is greater than 100 on a downshift or upshift to 3rd gear (128=0 or normal operation)DTC P0733 diagnostic runs continuously once the above conditions have been met.
DTC P0733 is a type A DTC for 2000, type B for 2001.**Applicable to vehicles built after June 2000.
Diagnostic AidsImportant: If DTCs P0745, P0746, P0756, P0758, P0761, P0763, P0766, P0768 or P0789 is set, diagnose that DTC first. A diagnosed PC solenoid, shift solenoid 2, 3 or 4 low/high circuit fault DTC may have caused DTC P0733 to set.Important: If a shift solenoid performance DTC P0783, 4th gear stuck ON, is set, diagnose that DTC first. A 4th gear stuck ON may cause no 3rd gear, no 2nd gear, or TCC stuck Off.
Refer to Pressure Ports - Air Check and Parts Description for pressure apply points and for component/location description.
Possible causes of no 3rd gear are listed in the flowchart on the succeeding page.
Verify TRANSMISSION ISS and TRANSMISSION OSS read correctly on Scan tool.
Make sure the pressure control, shift 2, shift 3 and shift 4 solenoids are not intermittently sticking. A sticking shift solenoid 4 may cause 4th gear to be applied from an initial start resulting in no 3rd gear. Audible sound should be similar for all solenoids. A muffled tone indicates the need for replacement.
Check this pinout HERE
P0734 refer at ratio 4 gear, and the rocedure is the same.
Hope helps.

I recently performed a transmission fluid flush (pan and torque converter) and swapped out the filter due to some problems I was having shifting from 1st to 2nd. After changing the fluid, the problem was...


One thing that is rarely posted is any repairs and or instructions on doing so. For instance the Solenoid pack is often suggested as a replacement, and you can buy them on e-bay, but no instruction on how to replace one. Amazing. I can fix anything! Just take it to the Tranny Shop..... Makes me think that the only answers put on here are by Tranny Shops.

Trans slips between 2nd and 3rd shift


MV could be the problem. Always work thru issue before buying ANY can of additive. Generally those things just mask the issue..not fix it. Change your fluid,and if that doesnt correct it,then take it in and have the tranny bands tightened. most shops do this relatively in expensively.
