TRANNY SLIP

2003 Saturn Ion

Transmission problem
2003 Saturn Ion 4 cyl Front Wheel Drive Automatic 127000 miles

the tranny feels like it slips or hesitates when accelerating slowly from a stop. The RPM's do not drop but the car slows for a few seconds.

I had a feeling you were going to say quad coupe that mean's you have a vti transmisson which is a piece of junk. The same transmission the 4cyl saturn vue's have I have replaced many transmission side cover's for that code. There is even a Bulletin for both the vue and ion about replacing the side cover for that code. You have to remove the transmission and take it apart the side cover contains you belt and input and out put shaft's it's a major repair and a very costly one. Here's the bulletin you will also have to have your transmission pressure tested to make sure you don't have a pump or valve body issue as well I have bad valve body's cause the side cover's to go bad and a few bad pump's.

Supercede: This bulletin is being revised to add additional Correction information. Please discard Corporate Bulletin Number 04-07-30-024D (Section 07 - Transmission/Transaxle).

Condition

Some customers may comment on the vehicle not moving in the " D" (Drive) or " R" (Reverse) gear selection positions. In many cases, the transaxle will also produce an audible grind or whine noise when attempting to operate in drive or reverse. The Service Engine Soon (SES) telltale may be illuminated with DTCs P0741, P0742, P0841, P1756, P1758, or P1882 set.

Cause

This condition may occur when the VT25E transaxle belt has malfunctioned.

Correction

1. Disassemble and clean debris from the transaxle.

2. Inspect the front differential transfer gear, drive pinion gear and the front differential carrier ring gear for excessive wear or damage.

3. Inspect the bearing assemblies on the front differential transfer gear for damage or wear. If a bearing assembly needs replacement, refer to Front Differential Transfer Gear Bearing and Cup Replacement in SI.

4. Inspect the drive pinion bearing cup on the transmission case assembly for damage or wear. If the bearing cup needs replacement, refer to Front Differential Transfer Gear Bearing and Cup Replacement in SI.

5. Inspect the drive pinion gear bearing cup on the torque converter and differential housing assembly for damage or wear. If the bearing cup needs replacement, refer to Front Differential Transfer Gear Bearing and Cup Replacement in SI.

6. Place the front differential carrier and the front differential transfer gear into the housing.

7. Rotate the differential housing several times in both directions to check for knocking, gear bind or movement caused by small areas of damage (nicks/chips) on the gears. If the gears do not rotate smoothly, replace the differential carrier and the transfer gear. Refer to Front Differential Carrier Removal and Front Differential Transfer Gear Removal in SI.

8. Re-assemble the transaxle with a new case cover assembly. Refer to Case Cover Assembly Installation in SI.

9. Flush the cooler lines using the flushing procedures in Corporate Bulletin Number 03-07-30-022.

10. Install the transaxle in the vehicle. Refer to Transmission Replacement in SI.

I am having a similar issue w/ my 2004 Saturn Ion 3 Quad Coupe--in the bulletin you reference above, it includes the P1882 code that we got when we ran the diagnostics last week. The car goes up to about 40 MPH and that's about it. The "whining" noise also sounds like something we hear as well. I have a mechanic friend, so obviously that would save a lot of money in labor, but do you think it's worth it to try and repair this vehicle? About how much would you estimate total repair costs to be in your professional opinion? If you don't mind of course : )

I'm between a rock and a hard place as this car has been really good to me over the years. I got it in 2004 and this is the first time it has ever broken down on me. The only maintenance it's ever needed was tires and a new battery last year, and of course routine oil changes and a tune up. I handed the car down to my husband last year and I hate to just throw in the towel, but we simply cannot afford to invest in major repairs if it won't be worth it in the long run. Thank you for ANY input, I would really appreciate it!
