tranny ?

[celica kid]

this has been on my mind for a while.. wheneva i am just going along and i have the need to downshift say like into second or somethin to catch like a yellow light my gears grind very hard core if i try to put it in second above 33 mph! i know that cant be right so i was just wondering what was up with that... i think i read something about syncrodes or syncroides or somethin like that... haha any ideas?

with my 92' celica I never go into 2nd if I am going above 40mph. any obove that the gears won't go In nicely and would grind if I forced it in. at 38 it goes in flaulessly. I think your shifting ring is bent. That is caused by cramming style shifting.

yea it has to be somethin like that but what trannies are on the mk1? cuz when i drive my bros mr2 i can shift from like 45 to 55 down to second.. i would really recomend it but it goes in with no problem... i guess i need to look into it some more

Up until 92 Toyota used weaker syncro's that wear out easily if you like to slam gears. The way syncro's work is that they need time between shifts to spin up and match speed. This is why I don't run a short shifter and bang gears on a daily basis, although my tranny could use a rebuild. Anyway, there are two things you can do, the first is to switch to a synthetic tranny fluid, it WILL help, but how much depends on the condition of your tranny. GM Syncromesh is regarded as some of the best shit to use. It is a little pricey at the dealer though, and I've heard that Penzoil synthetic and Syncromesh are the same thing, do a search with Penzoil and Syncromesh, you'll find the answer. The other would be a rebuild.

soo are you saying that i need to change out my syncros too?? or is that what you were talking about when you said the rebuild... *quivers at the thought*

To change out the syncro's, you gotta tear apart the tranny. It makes sense to inspect and replace anything else thats broken along the way, which is a rebuild. The syncro's are cheap, like $50 or so. Try the fluid first.

damn all that work just for small parts that cost 50 bucks.. yea its worth trying the fluid first thanks man
