The non-turbo MR2 was available with a 5-speed manual or 4-speed automatic transmission. The Turbo model was only available with a 5-speed manual transmission. In 1993 the Turbo’s manual transmission was improved with triple cone syncros on the 2nd and 3rd gears. 91/92 Turbo transmissions tend to wear out 2nd gear fairly often, and this is an especially common occurrence on high mileage MR2 Turbo cars.
The grind associated with hard shifting due to syncro wear may be alleviated somewhat by changing the transmission oil. Many owners have found that Redline MT-90 transmission oil reduced syncro wear and made shifting easier.
