Yes, Gear box doesn't like to shift at Highish' RPM's. You have to muscle it a lot more that you should and you don't have a good feeling about it sometimes. It is a Tremec TKO 5 speed (3550) and great for power capacity, but not for shifting. I have a replacement 4 speed Tex Trans T101A straight cut gear box that I will replace it with when the motor has to come out. The other problem is the TKO is a bit large for the mustang and you get a bad vibration from the drive shaft angle that can only be corrected by cutting the trans tunnel. The 4 speed will fix all that...hopefully :-).

Thanks

Sandy
