Well ..... I have to find out ...
Since last Wednesday our GMC, The Flying Dutchman, came to a stop at Seguin, TX ....
I already experienced shifting getting worse, sometimes no 3 gear in the days before, but at that point manually "helping" ... helped....
On the Wednesday morning it was cold, coming from a nice but also very cold stay at the Alamo City RV Park of 2 days, bringing the shifter from P to D
was very difficult. Much resistance. Driving .... only till second gear. On highway I only drove at 3300 rpm, about 55-56 mph (GPS reading)
Normally my oil pressure was about 40 psa, now 35 .... and as I approached the exit at Seguin, TX, it dropped to 20psi and seeing that, I instantly
took that exit, whilst rolling on that exit ramp it dropped to almost zero. I could swing in a nice parking spot between some trucks an switched the
engine off.
No overheating, nor temperature elevation on transmission temp meter, no smelling. Only I thought I heard in those last seconds a very light rattle.
Checking under the hood, there was some coolant got out against hood and dripping on ground, not excessive.
Checking oil, level still almost max. Transmission, good, red and not hot or smelling.
BTW before the start of this trip, all oil, transmission oil, filters, alternator, checking, new gasket with block off plates was done in Tuscon.
After consulting Alex and Espen, they advised me let it cooldown, 1-1,5 hours, then start it look at pressure and listen carefully.
I did, pressure up to 35 psi, but again dropping. And we heard a little rattle / knock ...
To summarize .... waited two days for the right wrecker, a Landoll with winch, luckycould spend the night in nearby motel, had food and gas station at
hand ...
And not to forget the help of several GMCers from around !
Billy, Stephen, Paul and Budd ... they managed to get me at Friday to the shop of Don Virta in Cedar Park, who promised me to get the job done, he is
going to get engine and transmission out, the whole clip ...
We decided to rent a MH, for 4 weeks, drove back with the help of Paul, to San Antonio, so we could continue our trip to Tallahassee GMCMI Meeting and
back .......
So the Flying Dutchman is immobilized for the time being, but I hope that he will come out of this, better and stronger then before
And to answer the question, asked here ... I don't yet know but we will see ... a down payment is already paid ....
