REPAIR PROCEDURE:
This bulletin involves removing the transmission assembly from the vehicle and replacing the 3rd input gear, the 3/4 synchronizer assembly, and tie strapping the shift cables.
1. Follow the procedure outlined in the 1995 Neon Service Manual (Publication No. 81-270-5025) for the NV T350 (A-578) Manual Transaxle, Pages 21-7 & 21-8, and remove the Transaxle from the vehicle.
2. Starting on Page 21-9 and continuing through Page 21-16 of the Neon Service Manual, disassemble the Transaxle down to and including disassembly of the Input Shaft Assembly.
3. Starting on Page 21-24 of the Neon Service Manual, reassemble the Input Shaft Assembly using the new 3rd Speed Gear and 3/4 Synchronizer Assembly provided in the repair package.
Also, do not re-use the Snap Rings removed during disassembly. Select the thickest Snap Ring supplied in the repair package that will fully fit in the 3/4 and 5/R Synchronizer Hub Snap Ring grooves.
4. Complete the reassembly of the Transaxle following the instructions listed on Page 21-27. Use new Roll Pins supplied in the repair package when assembling the Crossover and Selector Levers to the Transaxle. While still on the bench, make sure that all gears can be selected and the Transaxle is functioning properly.
5. Install the Transaxle into the vehicle. Fill the Transaxle with Mopar Manual Transaxle Fluid (MS 9417) P/N 4773167. Use of other type fluids could result in hard shifting, gear or Synchronizer failure.
6. Install the Transmission Shift Cables to the Transaxle Bracket using the two new Clips (P/N 4269830). Install Tie Strap (P/N 6015756) 7" forward of the Cable Routing Clip (See Illustration). Pull the Tie Strap tight enough to make the Cable Foam Sleeves contact each other. Clip off the excess Tie Strap lead.
7. Perform the Gearshift Cable Crossover Adjustment following the procedure outlined in the Service Manual on Page 21-4.
