And define rev the engine? By that did you mean you had delayed engagement? Delayed engagement could be caused be lots of things. (Most likely your 1st gear transmission band needs replaced.) if you forced your transmission into gear while its having an issue building up pressure for first gear, that could definitely have destroyed your band, and will need rebuilt. If it works with reverse right away it's more and likely not a pressure problem though. Since the transmission needs the most pressure in reverse. Has the car ever been tuned?
