T5 tranny, HARD to get in gear sometimes..

My stock T5 tranny is hard to get into gear sometimes. and other times, it wont even get into GEAR! like its being blocked by something! so i just play with it for a couple seconds and then it gets back in gear, other times, it goes nice and smooth and when i go into reverse is makes a nasty grinding sound unless i put it in first then slap in in R it goes smooth. someone said something about a selaniod going out. im not sure at all im not a M/T guy but can anyone help me out please?? thanks for all info or opinions..

Re: T5 tranny, HARD to get in gear sometimes..

As far as the "not going into gear" complaint, that's hard to guess at. Sounds a bit like something about the shifter but it's hard to tell.

i put it in first then slap in in R it goes smooth
Right; same as any other T-5, or for that matter, any other manual trans made before about 1990. Reverse is not synchronized, so if you just push in the clutch with the engine running and try to jam it into reverse, all the trans guts are still spinning, and there's no synchronizer to match their speed to the speed of the reverse gear, so it grinds. Just always put it into a forward gear (any forward gear will do, since they're all synchronized) before you go to reverse.

You have to shift into gears ar certain speeds then it will be smooth, or else you cant shift (well its harder)

Normal behavior

Sounds like the clutch my not be disengaging all the way. When you are at a stop, is it hard to get it in first? How much clutch pedal do you have? Does it start to engage? or Right off the floor, or up toward the top?

OH NO! it has nothing to do with the clutch pedal, its all in the SHIFTER. its the shifter that will refuse to go into gear. ill have the clutch pedal all the way to the firewall and it will still refuse to go into any gear sometimes. so i dont know what the deal is. and thanks for the R info sofakingdom. also the clutch pedal is stiff as F*CK is there a way to make it a bit softer? i really dont mind but when i drove my buddies 4 banger i barely pushed in the pedal and it went in and when i shifted gears it was so smooth. the guy i bought it from said it had a hydralic clutch?? or something along those lines. so i dunno! lol.

Your clutch IS hydraulically actuated, same as most modern cars (except for cheeep POSs like Frod, who uses a cable).

The reason your clutch is stiff, and his weenie little 4-popper's is light, is because his motor has about a third the torque yours does. Therefore needs about a third as much strength connecting the engine to the rest of the drive train.

Try driving a REAL 450ish CID muscle car sometime. You'll be grateful for the lightweight clutch that comes behind these 305s.

well the clutch isnt much of a big deal, im not a skinny dude so it doesnt kill me in traffic. BUT i know that the shifter its self inst supposed to REFUSE to get into gear. what part of the tranny or piece should i replace to fix this if anyone knows? i would like to drop the tranny out and try to replace it if i can and replace the mounts while im at it.

Re: T5 tranny, HARD to get in gear sometimes..

You don't have to take the trans out to do either of those things.

You can get to the shifter by taking out your console, and removing the rubber boot.

If you get up under the car, you'll see the mount, at the rear of the trans, where it sits on the crossmember. Very very easy to change. I highly recommend NOT getting a stock replacement one; get a poly one from Energy Suspension or Prothane.

Same for the shifter. The stock one is total crap. If you're going to go to all the work of fooling around with it, just replace it. It's one of the easiest mods you can make, and makes one of the most significant improvements possible to just overall how the car drives.

From what you're saying it does sound like it could be the clutch dragging, stopping the synco rings letting you get the car in gear. Or it could be the rings themselves but i would be odd to have the problem in all gears then. Does the clutch engage near the floor when you pull away? It could be worth checking the clutch fluid.

Let me paraphrase.
You go to put it reverse or any other gear and it feels like something is keeping you from moving the shifter sideways, then when you push the shifter up or down, If feels like it goes into a gear, but its real gritty. Some times you get the shifter to the reverse spot, start letting out the clutch and the car moves forward. While other times you let out the clutch and it stalls?
If thats the case, what is happening is that the interlock plate on the shift rail is worn, and sliding out of place. So you get three symptoms one is the shifter that feels like somthing is stopping it. The other is the abitilty to get the trans into two gears at the same time, which locks the trans up.
Also when you do get it into reverse and move it back wards you get a clashing noise.

To fix this you will have to pull the trans, knock the pin out of the offset shift lever and shift rail, then pull the tail housing off, then replace the worn interlock plate ( it look like a octagonal collar with slots) that fitts over the shift rail and some forks. And any other worn parts in the area.

Number 9 in the pic aslo may have to replace 8 as well.62388924.gif 62388920.gif

Re: T5 tranny, HARD to get in gear sometimes..

could be a faulty clutch or possibly you may need to adjust the clutch fork, or possibly need a new slave cylinder
