project 88
I have 99 oldsmobile 88 50th ann and its at 85k. I bought it at 75k last march and its been my daily driver.
Worked done so far:
Iridium plugs and wires, air and fuel filter
IAC replacement and throttlebody cleaned
idler pulley and coolant elbows
Issues:
When cold it drive ok but hard shifts as temp rises above 150 and sometimes it missfires really bad from a dead stop take off but if i unplug battery and drive it will shift ok for about 2 week or so (but shifts are long). When temps outside where in the teens here the temp gauge didnt go above 160 and hard shifts only happened some times but the temp outside was close to 50 and the car hard shifted after just a few mins of driving. Safe to say solenoid failure? The person who owned it said his girl drove it and she is a hard on the gas kinda driver so im just leaning towards a rebuild. Was quoted $1100 - $1500 (if to high stop me). When talking with the shop he said valve body update would be done with the rebuild. If theres anything else to look out for or would improve durability please let me know, would like to do this rebuild only once. I will try an additive for the trans to see if it can help shifting untill then. Fluid is brownish red but doesn't smell burnt btw and is full.
Plans:
upgrade stereo and speakers
Different wheels (17 or 18s should do. Ideas welcomed)
switch to synthetic oil and trans fluid after rebuild
Maybe New color
I want to keep this as a daily drive for as long as possible, would love to maybe swap a L67 in at some point if it comes along for the right price. ( actually just seen a 01 regal gs for 600 on CL bad supercharger) Will have pics as this project moves along.

i would imagine you thermostat is bad, change that and it should run better at about 195.
if you want to do an l67 swap, you want one that has a good supercharger. the bodies get rusted out, you see ones around here that have good whole engines all the time.
