Just purchased a 1998 A4 1.8t Quattro with 102K miles (for my newly licensed son). Spent some time searching archives on this site and learned a few things about some of the issues I am seeing with the heat and heated seats.

Question I have is on the transmission - when it upshifts I see a brief 3-400rpm increase as it shifts to the next higher gear. Is this normal? Would it be part of a chip mod, or am I seeing transmission slipping? I have read all of the archive comments about transmission fluid servicing - don't know if that's been done in the lifetime of the car.

Where's a good place to purchase parts online - OEM and aftermarket? Need drivers side lower door trim, and rear passenger also.

 

check out the 'audi links' sticky at the top of this forum...the transmission problem you're describing sounds more like a throttle problem to me, i'd start at your throttle body.

 

The more I drive it - the more it feels like slipping between gears. I am taking the car to the dealer for service next week. Looking at timing belt, water pump, and whatever pulleys and stuff that may need service while it's there. I am also going to have the tranny fluid level checked, and the radiator flushed/refilled - along with a heater check.

Why would you think throttle body?

Thanks!
