I know this is certainly not the only entry because of the switching problem… so my blazer switches into the next gear only at very high speed. even if I give very little gas. so about 50 kmh in the 2nd and 85 in the 3rd, no matter if warm or cold. underpressure is there (ventilation can be improved) jez has it at the top of the engine at the suction bridge where the gas train goes in the driving direction right so small part where 2 underruck hoses go one of them (the top) goes to the transmission . the other one in part looks like a large underpressure box under the air filter at the back of the engine. soo I’ll ever renew the two hoses. then jeman knows if the hose where from the transmission really comes to the top connection? what’s that for a built-in? and then still a thing my gas pedal has a kickdown switch in the top of the peal. but if I completely step through the pedal it doesn’t get to the switch there is about 1 centimeter of air in between… must certainly also ni doesn’t the switch have to switch to pass through or does it only turn on when pressing? would be very grateful for a few tips
