What are the common problems with the 1993 Toyota Supra's transmission?

Question

Accepted Answer

Great question! The 1993 Toyota Supra originally came with the R154 5-speed manual transmission, but this particular car has been upgraded to the stronger Getrag V160 6-speed manual. Let me break down the common problems for both:

**Original R154 5-Speed Issues:**
- Worn synchros (especially 2nd and 3rd gear) causing grinding during shifts
- Weak transmission forks that can bend or break under hard use  
- Bearing wear leading to whining noises, particularly at highway speeds
- Input shaft seal leaks causing clutch contamination
- Reverse gear lockout issues making it difficult to engage reverse

**Getrag V160 6-Speed Issues (what's in this car):**
- Shift fork wear causing difficulty engaging certain gears
- Synchronizer ring wear leading to grinding or crunching sounds
- Transmission mount failure causing excessive movement and vibration
- Clutch release bearing (throwout bearing) failure causing squealing or difficulty disengaging
- Oil leaks from various seals as mileage increases

The good news is that the V160 is generally considered much more robust than the R154, especially for modified cars making higher power. With 99,980 miles on the clock, this transmission has proven itself reliable. The recent service history showing fresh transmission service is also encouraging!

Would you like me to help you find similar Supras, or do you have questions about maintenance for these transmissions?
