so i know very little about tranny's i was wondering if any body has any ideas. so here's what happened. i was driving like normal home from work, and pulled out of an intersection. i excellerated a little harder than usual but i wasnt trying to smoke my tires or anything. when suddenly i hear a lound pop and my car wont respond when i accellerate. when i pulled over i discovered i had snapped my waterpump/alternator belt and my power steering belt was twisted around alittle but still intact and now my car wont go into gear but will go into park just fine, all the other gears are just neutral. my linkage looks good and as far as i can tell the vacuum feels good. i replaced both my belts and my engine is running like a champ. i have no idea whats going on. any thoughts?
i assume you checked the fluid level also check trans lines near pump maybe the got crushed closed then pump broke
i did indeed check the level. it's good. also the lines seem to be fine i havn't checked the pump to see if theres pressure but i did feel the lines while it was running and i think there was pressure going through. im going to replace the vaccuum modulator jsut to see whyat happens.
ok i just replaced the vacuum modulator and checked the pump and reset the detent cable still no bueno. the pump was going strong and the old vacuum modulator seemed like it was still good i replaced it any way. this was the first time iv'e messed with a detent cable though. im considering replacing it just for good measure. how would i check to see if the detent cable is stuck in the engaged position?
One way I can think of is to visually inspect the end of the cable near the carburetor or pedal linkage under the dash, however yours attaches. First make sure it's attached properly. From some point between closed throttle and wide open throttle, the linkage should pull the cable end from a resting position. Then when the throttle is closed again, the cable should retract "home". Another check would be to drop the pan and visually inspect the mechanism that the cable attaches to. It's a simple pivoting bracket on the valve body that depresses a valve, a spring behind the valve retracts the cable again when throttle is closed. Check to see that the bracket and valve are moving freely for their full range when the cable is actuated from closed to open throttle. Devon
I've never had a detent cable stick open so, as Devon suggested, check that. However, even if the cable broke your trans will still work but the shift points will be sooner and you will have to manually shift it to get them later. I hate to be the one to say it but I don't think your problem is going to have a simple fix. The last time I heard a loud snap and the car wouldn't move, I had blown the rearend. I'm not necessarily suggesting that is the problem but one thing that does come to mind is this: You said park worked, does it hold the car? Have you jacked up the rear and tried to run it through the gears to see if the driveshaft even tries to move? I'd look there, and if it doesn't move then you're probably going to need a transmission or a rebuild. Sorry, but it happens.
As much as I hate to tell people bad news, I have to agree it may be something more along the lines of "catastrophic". Hoping it's not the case, though. Devon
YEs it keeps it from rolling. I gave up and brought it to a shop yesterday. I think its the torque converter. I guess ill have to swallow my pride on this one. Thanks for the help gents.
If you go that route, there is an adapter. But, realize that the case (not a bell housing) is common to all GM except Chevrolet (all lines) and GMC trucks. That case is way common.
noted, i just found out the bellhousing is part of the case. so if i got this correctly i should be able to (assuming i find one with the right bellhousing bolt pattern) put my old extension housing and yoke on the new transmission and pretty much just pop her in. in a matter of speaking. or do i need a different torque converter as well?
im waiting for the shop to tell me if its the just the converter or not, im just thinkin ahead if it needs a rebuild. i might just swap it out and rebuild my old one jsut cuz ive never done it before.
