i have a suncoast tranny, and i put it in about 4 months ago no problems, when i went to change my oil today there was a crack by the bottem flywheel cover bolt (bout an inch away from it) and it ran almost to the very top of my tranny about 1-2 inches away from my bolts, and its seperating, what could have caused this? and any suggestions on what to do, cuz i dont want to buy another tranny it costed me way too much... can i buy just the front piece of the transmission? 99 f-250 juice with att. thanks for any help...

what kind of warranty did this tranny carry when you purchased it? mile/month wise. my freind has an aftermarket tranny, he blew it up in six months and they replaced it under warranty

I'm sure they will warranty it. But, are just talking about the bell housing?

Sounds like ether very hard shifting or there was something in the way when it was bolted to the motor. The guts can be put in a new case for not to much money. I have looked at cleaned and checked cases on Ebay that sell for about $100. Sucks to pull it so soon.

well suncoast would warranty it if it was internal, but not external, so instead they said if i bought a case either from them or had it shipped with my tranny that they would pull my internals, replace any worn parts, line pressure test it, and dyno it for $300 so i cant complain too much its just a bite in the *** to have to buy a complete core tranny for the case at like a 500 dollar cost...then 300 to ship it from gillette wy. to florida...

and i also twisted my drive shaft i found out after i took it in to be checked after replacing three sets of u-joints (i thought it was the extremely hard shifting that took them out) but it was twisted 1/4 inch, yes due to hard shifting haha and first thing suncoast asked was if i drove it with a bad u-joint or bad driveshaft cuz thats what breaks the case away from the engine... so yea my bad...

Well at least they will help out, thats something. Who ever you have do it I would have them soften up the shift a bit, pull about .025" worth of shim out of the valving.

i wonder if this is my problem. i was just about to post asking about this. i have broken 3 cases in 3 months. first i noticed a leak at the rear of the tranny before the extension housing, then a crack on the bellhousing.i made an 8 mile round trip to buy the only housing around me and pullend an all nighter to swap the internals. i got in too big of a hurry and cracked a parts going back together, but i pushed on "just to see". i ended up burning up all the clutches. so i had it completely rebuilt by my transmission guys since i didnt have time to fool with it myself anymore. i had a sonnax shift kit and boost valve put in, along with a few other internal upgrades and a billet triple disc converter. i got the tranny back and it always had a small leak in the rear. i found a crack in front of the extension housing that went from one side to the other. and all the bolts were finger tight. so i got another new case, swapped out all the parts and have been riding on it for about 3 weeks. yesterday it started making a noise at idle and looking at it today, i found another huge crack in the bellhousing, just like the first time it broke. the shifts are hard, but not enough to do this. my front driveshaft has a tiight spot in the u joint, but the rear seems fine. i have another case coming and i am sending both of my driveshafts out to be checked. hopefully i can find this problem before blowing another case.

After replacing two more transmissions i found out it wasnt my driveshaft, it was the engine mounts being busted. i noticed when i put in the transfer case that in order to even get the bolt back into the sloted holes in the cross member that i was lifting the rear of my engine. After checking it out i noticed the engine wasnt even on the supports anymore. since i have replaced them i have put probably 50,000 on my truck with no problems... so there is something to also check out...

thanks for that. when i busted the third case and realized it wasnt a fluke and that i had a real problems, the mounts were the first thing i thought of and had planned on doing when i put the new tranny in. honestly i have never even laid eyes on the engine mounts before. when it broke the first time, i had winched a vehicle onto my trailer. i forgot to take it(the vehicle i was winching) out of park and it actually pulled my truck bact to it about 10" before i had realized it. 2 hours later i found the crack in the bellhousing. i got everything swapped over to the new case, and it broke at the tailhousing. those bolts were finger tight so i kinda blamed it on the builder, but now realize that may have been in error. after this break, i am sure there is a real probem somewhere and its not a fluke. i planned on replaceing the mounts anyhow, just tot kind of shotgun the problem. thanks for the info.
