We are german "Airstreamers",
,we bought a 345 classic in april and drove it cross country to the port and shipped to Germany. A wonderfull trip!
The rig is a 1986 classic 345 with 454cid engine and standard TH 475 (?) 3 speed tranny.
Before we left, The previous owner had it completely checked from Chevy truck service, with engine tune-up, oilchange in engine+tranny. Than the coach was checked from an Airstream dealer for eventuel neccessary repairs! (Adventure RV in Davenport/Quad Cities. I do not really recomand this shop anymore...! Many sefaults in repairs, not for a good rate, not very quick
We have installed there also a Bank's Power System to improve gas mileage. Our baby was extremey well climbing hils, gas mileage also OK. With the "sweet spot" 65-70mls/h we got 10mpg.
Now we have a serious problem:
After we drove 1500mls cross USA and a few trips here in Germany, i had to realize some noise from underbelly with "bumbs" on the chassis.
I had to realize, 2 of 4 bolts from the transmission mount were gone, the 2 bolts in place were "handtight" only!
I fixed this, but i realized some lack of power, during accelaration. It became worse and worse, then we found unnormal noise, coming out of the torque converter, sounds like a metal fan is "scratching" the radiator
Coach is now barely drivable, very slow, impossible to travel anymore. I am afraid to use it more and more, do not want to "kill" the tranny!
Now my question: What is the torqueconverter i will need. The rig has much more torque with the Bank's system. I will add later also an Edelbrook performer kit for more torque (Intake manifold, camshaft, 750cfm carburetor).
We also tow a 6000 lbs trailer later, so we will need something VERY SOLID.
What do i need, what is the recomended "stall speed", where can i get this ?
