Something weired happened to my tranny!

[alqatan]

Hi there, hope I get an answer this time
I rised the boost till 25 psi and I'm so happy with the power I got with c16 and GM MAF, I tuned the car by S-AFC and left all the setting in zero on the MAFT because I didn't want to keep going to the hood till I tune it right!

Anyway I love to spin my car alot, I was so happy because it was spinning like hell with that psi, actually with 9 psi I used to spin 1st, 2nd gear but the tires weren't that good I had Dunlop, now with Michlen I wasn't able to spin at before in the 2nd, but with 25 psi, I spinned in a new gear which is 3rd gear, I'm so happy with the power, but I should let the 2nd gear hit the limiter so when I ever I shift to the 3rd I don't get that ugly lag, by the way if you didn't read my old posts I have T3/To4e 60 trim, the last time I shifted to the 2nd and floor it I got a very bad wheel spin then HAS A SOUND LIKE BEARING, actually I was very worried about the engine I though it was the engine and I felt the car hitted a break after this sound came, I was in front of my mechanic garage, he said this isn't your engine I thought I had this power to bent or breaking connecting rod bearing, but then I relised the sound is coming from the tranny, we thought it might be the shafts then as I said it's the tranny it self, when the car in Normal mode I can shift through all the gears and every shift feels the same as it was also the reverse is the same but when ever I try to move there is something like locking the gear in ever shift actually I only tried 1st and reverse moving the car but I can move the car reverse more than 1st but it's still locking with weired sound like shaft broke, I'm sure nothing happened to my fork or ratio or sencro because I wasn't power shifting and all the gears seem the same while I'm idled, what do you think I've break and why did I get that problem?

PLEASE GUYS I NEED YOUR HELP, I e-mailed TRE AND SHEP about having racing tranny, as you know I can't ship my tranny then send it back to me because I'm living in Bahrain, very far away from US and it will take time and alot of money till it reach there, so I was wondring if I can buy a tranny which builted by them but I want FWD because I'm racing for top speed and I need the long short ratio in the first gears or I'll spin more, they both said they have AWD tranny which need to change the flywheel to match the new tranny and to make new hole for something else

Please guys help I might be able to fix the tranny, what happened exactly and what should I do, we can fix trannies over here.

Thanks

You beat your car like an ugly red-headed stepchild, and now you wonder why you broke it?


Is this a serious question?

Also check your differential. It might be missing some teeth too. That will happen if you get alot of wheel-hop while spinning your tires. Wheels hop is the #1 cause of breaking trannys like you did. Rebuild it w/ a double syncro in 2nd, install an LSD, and drive it alot easier. Spinning you tires only breaks mecanical parts and causes excessive wear on the tires. Nothing positive will result from always driving like that.......

Actually I worried of getting the same problem with SHEP tranny, I ordered two FWD rebuilded tranny, one is used the other one is new from factory, this is because Shep only have one used tranny to build with his racing stuff, I asked him to make it racing as much as he can, it costed me like 3650 USD for the used one and 4255 USD for the new one, does he ship the OEM parts again because I might install the OEM parts on my old tranny to make some money from selling it, I made it with longer 5th

All of these things are included in my new tranny
New 1-2 fork

New 3-4 fork

New Shepracing spec 2nd gear

New 1-2 hub/sleeve kit with double synchro rings

New 3-4 synchro rings

New 5th gear synchro rings

New 1-2-3-4 synchro springs

New input ,output ,and both drive shaft seals

New Input shaft bearings

New intermediate gear bearings

New roll pins

New end nuts

Shims for setting preload

New nylon shifter pad

The price for this rebuild/upgrade is $895.00

Other options include:

Heavy duty 3-4 conversion (93.5-99) - $300.00
Steel 3-4 shift fork - $80.00 each
Painted with cast blast or aluma blast - NOW FREE
Quaife+longer 5th gear ratio to get more speed so I can beat alot of other cars

I don't know if the things he is installing would include what I broke, because if it wouldn't then I might break that again and again, I wasn't power shifting, I wasn't shifting that much fast, but it had alot of wheel spin, I'm sure there are alot of fast FWD cars, I wonder if they break their tranny or is it because I used that wrong way, please help me so I don't get this thing again, it does cost alot for breaking tranny

Thanks for the help

I think you need the Muti stage MBC so you run a lower PSI to keep from spinning the wheels at lower gears\speed. Why would you even WANA spin the tires??? ur not going any faster. unless ur running Slicks, its not worth it.

Get a Quaife or a Kaaz LSD. It will eliminate much of the wheel-hop that could potentially destroy yet another tranny.
