Default t56 third gear issue

hey last night i was driving on the highway in 6th gear...not beating on the car, just cruising. When i got off my exit ramp i downshifted into 5th, fine. Pulled to a stop light and went to downshift into 3rd, and it would go in. Popped out. Every gear works totally fine, however 3rd gear will not grab.

I know that the fluid should probably be changed, but i cant imagine that would cause my 3rd gear to stop working.


please help

Sounds like a bent shift fork. Been there done that...

You probably have to get it rebuilt and when you do get a shifter with stop bolts to prevent from overextending gears thus leaving you with a bent shift forks and the synchro sliders from popping out. rebuilds can be had for pretty cheap around 700 bucks or so with upgraded parts like steel 3-4 shift fork, carbon fiber synchro rings, etc

alright now im really confused

so after not being able to get the car to go in, or stay in 3rd gear for a day and a half, last night driving the car i was at a redlight and put the car into 3rd gear. It seemed to want to stay in 3rd gear at a complete stop, so i started off at the redlight in 3rd gear, and now it works fine again.

just check on the shifter and you might wanna look into a rebuild sometime in the future to keep from getting stranded.

So why is it you make a 3rd gear start? Ive done this in extremes of weather( snow/ice) but August hardly produces any traction concerns. Seems you have other operator-related problems.Why is it you don't want to check the shifter?

i made a third gear start because while i was at the redlight the shifter actually stayed in 3rd gear without popping out. So i started in 3rd gear to see if it would pop out under load. It didnt, and now works fine. Seems like you may have some reading-related problems. but thats for you input, or lack their of.

Thanks for your rude reply , I thought of helping you- silly me .My reading skills are just fine but I do have a little trouble translating spoot-speak.BTW you should cover your own *** with spell check . Maybe what you really need is to drive your moms automatic Buick wagon.

Dude you really do need to read closer. He said he started in 3rd because he was so surprised he got it in that gear while at a standstill, that he wanted to see if the gear itself was working. There is nothing wrong with his driving.

All transmissions have their problems but the T56 is a hell of a solid tranny.

There's a member putting 950 hp through a stock T56. Its all about how you drive the car and maintain it.

Still, dropping the tranny is a pain, have fun with that.
