Well, thanks for all that info. Very helpful, as you can see half way down the third post, the code is there (W5M33-2-NPXV 91-94 Eclipse AWD 5spd mfg 6/90-2/94).
That's good that the ratios match and the VC wouldn't burn out, but my car was made pre-June 1990, June being when the trannies switched from 22 to 23 spline.
Is there way of putting a 23 spline post June '90 in my factory 22 spline car?
Thanks fellas
