Lost 3rd and 4th? I think i screwed up my trans.
well I was creating some smoke by a friends house yesterday and as I drove off when it shifted into 3rd the Rpms went up to around 4k at 30mph
I couldn't get it to go into 4th at all
I had to drive it in 2nd to get it home.
It's been sliping while shifting into 2nd and 3rd at WOT for a while now so i knew it was comming
So i figure i'm in for a rebuild what kit should i get or would it be that much better to just have someone else do it (still in school and low on $)
dunno if this helps any but it's a 95 Z28 A4 bored .030 over hotcam and lightly ported heads (and a few other suporting mods)
Thanks

you broke a main gear cog (name?) for your 3rd to 4th. Maybe even broke the teeth .I broke mine in my 5th to 6th and had to limp home one time.(without 5th or 6th) Mine broke right in the center of the shaft under normal driving. The tranny guy said that was a defect in the metal, that caused the break.

No he's talking A4, you fried a clutch pack and trans needs rebuilt. If you don't know what you're in for I'd take it to a good trans shop, you can save a bit by pulling the trans yourself. You CAN do it yourself if you're really dedicated but I don't recommend it, and in the end you probably won't save a whole lot. That being said, in order to do it yourself you'll have to either buy or build some special tools(spring compressors, seal tools, end play guage, etc) and make sure you get an ATSG manual. I went with the Alto red eagle kit when I rebuilt mine, and it's good stuff. In addition to the kit you'll need a band(think that was seperate) a new TQ converter and a new sprag. I also bought an upgraded pump kit, corvette band servo, shift kit and upgraded sun shell, but all that's optional. The place I ordered my parts from is gone now so I dunno about that.

I have a bud with the exact same problem. It runs through 1st & 2nd perfect and on the 2-3 shift, it's in neutral. We're running him out to Select Performance tomorrow. We're hoping it's just a solonoid or wiring problem. I'll post the results.

My friend's transmission was checked out at Select. Apparently, in the pan rail, there's a bleed off vent for the servo. This vent is a small hole in the pan gasket rail. The stock pan and gasket are notched to clear this vent. My friend had an aftermarket pan and gasket that didn't have the notch and the vent was covered up. There was even a GM bulletin noting this after they had some warranty and service issues caused by aftermarket parts.
It’s in the pan gasket surface just under the servo, the big round thing on the side of the case. This hole needs to be clear. Check your units guys! Covering this hole can cause the servo and clutch packs to hang up and wear out very quickly.
